Width, 41.50 in. The aim of the honing process is a nice crosshatch finish that performs superbly. High Performance, 0.440 in. The assembly process is much the same as previously described. The cam has a duration of .302 and a lift of .410. Head accepts long reach RC-12-YC or. Mostly true, but the French military used flatheads as late as the early '90s and "ancient" flathead technology has evolved to run over 300 mph at Bonneville. Tony Baron runs 10 degrees of base timing and 23 degrees max at full advance. Others prefer an original 8BA. Gasket for original Miller/Cragar cast-iron cylinder heads. The seat width is approximately 1/16 (.060) inch, shown here by the dull line around the middle of the valve seat. For the overhead valve cylinder heads on A/B engine blocks. The engine may "feel better" with 27-30 degrees total timing (as read on the crank), but Baron says "it slows up the flame travel. The pickup is carefully aligned with the pan rail so that the stepped flange in the pickup sits in the corresponding recess in the pan baffle. The Thickstun two-carb high-rise intake (today marketed by Baron) is an excellent street setup and it even provides clearance for the stock generator. As mentioned, the Ardun heads are likely the most popular, and for good reason. Compare this to the originals that were 1:25 to 1 and this will provide a 15% increase in valve lift, ready to go on your head. After 1953, flathead production continued in other countries, most notably in Europe, where the engine continued to be used in French military vehicles through the '90s. Bolts are being dropped into the corner holes to align the gasket properly. However, Rays engine has 1.6-inch exhaust valves and whopping 1.75-inch inlets. Part Number: DAC-15415. Interestingly, part of that room is devoted to engines that went beyond the simple flat-head design and utilized many of the various over-head conversion units that were available. The flathead's compression ratio is well suited to supercharging, and besides, what could be more hot rod than a blower poking through the hood? The valve assemblies were inserted into the block along with the C-clips. A professional engine builder such as H&H has well used air-powered tools, but electric drills (corded or cordless) and Dremel tools work fi ne. High-compression is the way to go. During the engine's first decade of production, when overhead-valve engines were used by only a small minority of makes, it was usually . Research has shown there's relatively little air movement over the base of the block. Some say that the NOS French block is the way to go, and in some ways it is. I mean, how hard can it be? Wear protective goggles and even a facemask to keep detritus out of your eyes, nose, and mouth. Now it's 2005, and the flathead's resurgence shows no sign of diminishing. If it boils, steam pockets form, and when you have steam, you'll get cracks. That was his entire shop. For Rays engine, H&H chose an original 4-inch Merc stroker crank that had been offset-ground 1/8 inch. You must still do a physical check to ensure against a miscalculation and to make sure that the valves dont hit the heads. Note that, because it is a race engine, it has no generator and, therefore, a shorter belt was needed. A wide variety of headers are available for flathead engines, which certainly should not retain the restrictive stock exhaust manifolds. Only 200 original sets are known to exist, but fortunately, Ardun heads and associated conversion parts are back, reproduced in improved form by Don Ferguson of Ardun Enterprises. The passages are oddly shaped, with some right-angled turns, with all sorts of nasty casting flaws. Spiral locks are little fl at springs that you pull apart and ease into the groove in the piston. Ultimately, there are equal-length race headers available from Tatom Custom Engines. The home of the Ford Flathead rebuilding specialist from mild to wild. Nevertheless, it had Sharp heads, a Navarro intake, and three Stromberg 97s. (Photo by Tim Sutton). $1,399.98. (Photo by Tim Sutton). SHARE THIS ARTICLE:Please feel free to share this article on Facebook, in Forums, or with any Clubs you participate in. Andy is an avid railfan and gets his high by flying radio-controlled model airplanes when time permits. Later versions were driven by a belt, but these are the earlier shaft-driven versions. Complete Flywheel and V8 Ford clutch plate $725.00 Cragar Four Port Cylinder Head for Ford B Engines Developed for street use, rather than racing, due to it's mild valve spring pressures, its 9:1 compression ratio runs smoothly on regular fuel. In addition, it has no fuel pump; an electric pump will be used instead. Machining required to fit Model A or B cranks. Whether planes, trains, motorcycles, or automobiles, Andy has immersed himself in a world driven by internal combustion. Required caps for installing Model A crankshaft in T block. According to Baron Racing, the limiting factor is not piston-to-head interference, nor even valvespring coil-bind-it is running out of cam bearing clearance for the lobes. As mentioned, there were two things to remember about this era EVERYONE was trying something new, and heat was the flatheads main enemy! A good supply of new French (really) blocks exist and outfits like Scat make new H-beam rods and sell cranks with up to a 4.5-inch stroke. Hilborn and Ardun Enterprises offer EFI conversions that look like old-time stacks but with EFI nozzles. The downside was, as Flathead Engineering's Charlie Clark puts it, street rods "began to look about as exciting as a belly-button-everyone had one. The clearance between the valve and the head needs to be at least .050 inch. Let the chips fly (and they will) as you cut into the soft aluminum with a cutting tool. Correct-length flathead 1.800 intake/1.600 exhaust valves are available from flathead specialists like Baron Racing. Even before Henry's breakthrough V-8s, and decades before the introduction of the Chevy small-block, these were the prevalent powerplants. New stainless valves are available from several sources. There was a 226ci engine used in lots of cars over the years with a max power rating of . If you liked this article you will LOVE the full book. The block has plenty of material in this region, so you dont have to worry about grinding away too much. In this case, a baffled oil pan from a truck is used; the baffle helps oil control and keeps the oil in the sump surrounding the pickup. Most builders convert the stock oil system to a full-flow design with a modern, remote-mounted oil filter. I am building an H series 226 for a 31 Roadster, I Found a vintage Knudsen aluminum cylinder head and 3 carb manifold, As far as I can find out Knudsen and Cyclone were the only mfgs. Flatheads need high compression because they don't breathe. The two ports immediately to either side are siamesed, and the gases exit to the bottom through the exhaust port. An inside micrometer is used to measure spring height. Instead of the more common lock rings, spiral locks are used to retain the pin because they offer better retention. The Alexander head was designed during World-War II and addressed the heat issue by moving the exhaust port up out of the block, but kept the stock intake port design. It was only at the very end of the flathead's reign that the first small four-barrel carbs appeared; back then everyone used multiple-carb setups. This is not the truck pan with the inspection plate. Offenhauser New Ford Flathead Cylinder Heads (2) 49X53 1069 400 Compression. A close-up of the Cragar style water pump illustrates five sealed roller bearings, ceramic seal and a four fin brass impeller. Be very conscious of this before you start grinding. Mooneyes also offers throttle-bodies that resemble Strombergs. This ensures that the bores meet the manufacturers specifications for the Ross pistons. In the middle is the new 1.6-inch exhaust valve, and to the left the giant 1.75-inch inlet valve, here with a test spring assembly installed. Besides, multicarb setups look cool. Large-diameter, unshrouded valves combined with a proper combustion chamber configuration and piston design are needed to promote the proper transfer area from the flathead's valves to the far end of the chamber over the piston tops. In fact, unless you have a badly core-shifted block, most of them can accept a whopping 0.1875-inch overbore (3/16-inch over standard). At around the same time, old-time hot rods gave way to modern musclecars and street machines. It will use a new oil pan and special bolt-on universal bellhousing that accepts most modern transmissions. any problems please contact service@stirlingkit.com Miniature Engineering Models that Run on Fuel While the first modifications to the flathead were not in the interest of performance, those very same components then helped to power flatheads well past what their creators had ever envisioned. Currently the most popular approach is running a big popup piston, but with a scallop on the side adjacent to the valves to keep the transfer area clear between the valves and the cylinder bore. Four carbs on a properly designed intake manifold offer the best distribution short of today's dry EFI systems. In fact, the growing flathead movement has basically sorted itself out into three distinct groups. It has lots of structural advantages internally that make for a much stronger head where the original Thomas head didnt have thick enough material to help reduce the possibility of blown head gaskets. If you've seen the video or pushed the "little red button" at one of our recent shows, you know how much fun it is to watch this four-in-line whine! Honing the block of this high-performance flathead follows essentially the same procedure described previously, but in this case, the tolerances are much tighter. This lateral flow severely restricts flathead breathing capability, although it does promote what today's high-tech engineers term swirl and tumble, which enhances fuel mixing and combustion. Tech help for our customers and Old School Customer Service! There's just a pulley on the engine, and he says it runs well.

You need the right amount of plenum volume and runner length to complement the engine size, camshaft, cylinder-head flow, and operating range. The solution is to raise the boiling point by upping coolant-system pressure to 17-21 pounds, using a modern crossflow radiator and higher-pressure cap. On Rays Navarro 3 x 2 manifold, Dykem was painted around the ports before the gasket was laid down. Length, Each. Add to Cart. Looking down through the intakes, you can see the beautiful job of porting. Stromberg parts as well as our own Drake Made items, many Ford authorized! Reams have been written about porting the flathead, because in factory form its a very asthmatic engine. It was there one of the flatty's Achille's Heels was realized. I'm wondering the hp, and if I could find a . The '39-'48 flatheads used a direct camshaft-driven front-mount distributor; '49-'53 engines use a gear-driven, vertical-mount distributor on the right-front of the engine. See all 42 photos. H&H started in 1972 with rebuilding all early Ford Flathead engines from Model A, B's, T's and V8 Ford Flatheads from 1932-36, LB's, 59A's, 8BA's,V8 60's, Lincoln 337, Lincoln V12's and Y Block Ford and Mercury.

This head has many improvements over the previous head. In some areas, theres quite a bit of material to be removed; less so in other areas. Because of the tight tolerances, the spark plugs should not protrude into the combustion chamber. A flathead with a 1946 block powered Ron Main's Flat fire to a new land speed record for its class at 302.674 mph. After removing the checking clay from the head, each compressed wafer is measured. Bulletproof rods for the Model B engine that accept Triumph TR-4 bearings. With some exotic tuning, it has been known to produce 700 hp, and not just for short bursts. However, they are a little more difficult to install and remove. These include the '39-'53 Mercury and '46-'53 Ford castings. Ready to install. There are only 3-4 sets known to exist, and looking at the second photo, it's easy to see where Mopar might have gotten the idea for the Hemi engine. Notice all the intakes on the right wall and youll see how kind the aftermarket has been to this iconic engine. The best balance has been the subject of debate for over 60 years. If youve never tried porting, you should probably buy a junk block to practice on. For starters, its the most modern casting available; theyre unlikely to have any cracks, they have thicker decks and main bearing bulkheads and larger main bearing caps, and they are already aligned honed. Sweat them on, no welding needed. TBI injection through billet Stromberg 97 carb-like throttle-bodies is available from Flathead Engineering. Theyve also been sending out newsletters, such as the most recent one highlighting some of the various overhead-valve configurations of the iconic flathead Ford engine that call the museum home. These second-design '38 1/2-'48 blocks (often referred to as "59A" castings) retained an integral cast-in bellhousing, used a distributor that mounts flush to the front cover with a horizontal shaft on the front of the engine and had insert-style main bearings but still used full-floating rod bearings (one bearing shell for each rod pair). In 1947, long before Zora Arkus-Duntov became famous for his work developing the Corvette and performance Chevrolet parts, he and his brother Yura designed what has been considered the ultimate flathead performance mod-turning the engine into an overhead-valve hemi. The company they formed to produce these heads was named "Ardun," an acronym derived from their last name. We make All your Model A/B Engine Dreams come true Seal the heads to the block using slick new graphite-impregnated head gaskets available from Best Gasket, Red's Headers, and Tatom. Before the heads are finally installed, a dial gauge is used to ascertain TDC, using cylinder number-1 (passenger-side, front). Tractor. You would expect the block to be hard, but it is surprisingly easy to cut if your tool is sharp and you lean on it. It will come with the clutch throw-out shaft and fork, including a new pilot bearing. Not all of the intake bolt holes have corresponding holes in the block. Its possible if you come at it from an oblique angle. Check the crank at every stage of the tightening process to make sure that it turns freely. Let's talk about four-bangers. Strombergs were the favorites, but Chandler-Grove/Holley, Zenith, and Rochester two-barrels were also in use. Because this is going to be primarily a race engine, H&H used Ross forged slugs with only three rings, which makes for a lighter, faster-accelerating assembly. With modern flatheads routinely putting out 250-300 lb-ft of torque, the original trannies obviously aren't up to the job. Small-block Chevy valves remain popular, but with reduced-base-circle cams they may be too short to permit proper lash adjustment. We will safeguard your e-mail and only send content you request. That necessitates larger, hardened valve seats and commensurate work hogging out the block to accommodate them. He hired H&H Flatheads to build the engine so that it can be raced again. Longer gears enable the M-15 to pump 25 percent more oil than the stock pump. Offset-ground means that the original 2.138-inch big end, or rod pin, journals were reground 1/8-inch offset and smaller to accept 2-inch bearings. The world's quickest flathead dragster, Ron Schnell's Slider, has run the quarter in 7.695 seconds; it's blown flattie dyno'd at 939 hp on a 60-percent nitro load. Sponsored. The stock flathead oiling system is marginal for performance use. (Admin - please delete if not allowed). Written by Greg Kolasa and Posted with Permission of CarTechBooks. Intake port work starts with a look at the intake gasket . The gases also pass in the opposite direction and exit through the small round holes to heat the intake manifold, which, depending on the application and/or intake, can be plugged off. But with modern solid cams and big stroker cranks, overall engine rpm and piston speed is considerably higher than the old stockers. On another stock block, you can see that the standard exhaust port measures just 138 inches. After all the machining, the intake was bolted down. CISON FL4-175 Flathead Inline 4 Cylinder Four Stroke 9,000 rpm RC Water-cooled Gasoline Engine 17.5cc Shipping update on 2022/10/14: this engine is in stock now, 6pcs for kit version, and 2pcs finished version. Filed Under: Flathead Engines, Ford Tech Tips, 2023 DiY Ford. With modern aftermarket cranks and rods using modern insert bearings, 5,500 rpm normally aspirated is not a problem, even with only three main bearings. Two things to watch out for are an extra water hole in the block and the lack of a breather standpipe in the block. The Total Seal rings are put into the honed block, and the gap is measured with a feeler gauge. Then, torque the nuts in sequence to the specified 95 pounds. As for cylinder heads, Baron, Edelbrock, Navarro, Offenhauser, and Sharp (now sold by Wilcap) all have their adherents. Intake ports are 1 5/8 inch diameter, O-ring sealed. Normally we'd title this section "Cylinder Heads," but on a flathead, the heads-having neither ports nor valves-only form the combustion-chamber roof. Finally, there are brand-new aluminum blocks and Ardun OHV conversion heads and valvetrains. There's a fine juggling act between compression and promoting proper transfer from the offset valves across the piston top. The mixture must follow a tortuous U-turn path out the block-mounted intake valve, over to the main part of the chamber above the piston, and then back out the exhaust valve. Heads arrive complete and ready to install. Find FORD 3.9L/239 Ford flathead V8 Engines & Components and get Free Shipping on Orders Over $109 at Summit Racing! Andy has been intrigued by mechanical things all of his life and enjoys tinkering with cars of all makes and ages. It used a Ford 116E iron cylinder block and a new aluminum cylinder head with dual overhead camshafts. This laborious process takes time and patience. Flathead Myths courtesy of Tony Baron Also note that the water pump is O-ring sealed. With most engines, increasing compression results in more power, but with a Flathead there is a point not only of diminishing returns, but a point where power is lost--and it's lower than you . The exhaust port can be ground out safely from 138 inches to 134 inches. The billet replacements offer more strength and rigidity. You can now build a brand-new flathead. However, the French weighs in at about 30 pounds heavier than an old block, and extensive port work is necessary. Free shipping. It has 7:1 compression, uses long reach 14mm spark plugs, like the Champion RC12YC or the RN12YC. Mike made sure that the oil feed holes and the hole for the fuel pump pushrod aligned. Box 53296 Albuquerque, NM 87153 Grade 8 nuts and washers. Ground with a 114-degree LSA and 112-degree intake centerline, it has 0.395-inch lift and 234 degrees duration at 0.050. When Ray acquired the car, it was still fitted with its 8BA flathead, but a few parts were missing. However, if your goal is a period-correct hot rod, you probably want a Detroit Ford and not a French Ford. Most hot rod engines use oversize valves. A guy was willing to sell me a ford flathead 4 cylinder engine. Our mission is the same as it always has been since 1985; to provide top-quality speed and performance parts for 1928-1934 Model A & Model B four bangers. Estimated Ship Date: Jun 29, 2023 if ordered today. Some fuel-injection setups even run distributorless coil-ignition setups. Possibly one of the rarest OHV conversions is the Stephens. Copper head gaskets are sold by SCE. "Joe taught me how to build these four-bangers to make them go fast," he says. This causes lots of turbulence in the chamber and better fuel burn. Ross, Wiseco, Egge, Arias, and others make pistons in any configuration you desire. Comes ready to install. You may lose as much as 30 hp above 4,500 rpm. Made of two sheets of .010 thick copper, rolled in the combustion chamber for a fire ring, and include .060 of E-6005 non-asbestos material for a total gasket thickness of .080. On the following pages, we'll take a look at some of the stuff available for the flathead and also cover the lineage, interchangeability, and secrets of this proud forebear of modern hot rodding. The whole thing starts with a Donovan aluminum block with five main bearings. Log style intake manifold for Two Stromberg 97's. This gives you sufficiently accurate timing to start the engine. This kit is designed with precisely located tabs and slots, and it goes together with a bare minimum of glue. The flathead blocks to get are those with a 3 3/16-inch bore. Baron, Edelbrock, Sharp (Wilcap), Navarro, and Offenhauser make both old-style heads as well as improved new configurations. No one runs the old weak stock ignitions anymore. Eventually you could build a whole street rod out of aftermarket commodity parts. (Left) This engine is a prototype of the flathead Ford engine that would be introduced in 1932. There is also an ugly governor mounting boss on the left-rear of the block that many rodders prefer to machine off. By the time Don reached his 16th birthday, he had already built a '29 Ford Model-A Roadster with a Cragar two-port cylinder-head-equipped . One solution is adopting a small-block Chevy damper. The clearance between the top of the piston and the roof of the combustion chamber is .063 inch, which is suffi cient and confirms the previous calculations. The Lotus-Ford Twin Cam is a Kent-based I-4 developed by Lotus for the 1962 Lotus Elan. The present-day Arduns are CNC-machined using high-grade 356-T6 aluminum, have refined combustion chambers, and improved oiling and valvetrain components. He gave them a good coating of engine assembly lube before sliding the new H&H high-lift race cam into place. The current incarnation is 3 inches taller than the originals and has smaller 1 1/2-inch ports (vintage versions had 1 3/4 ports, but the new casting is thick enough to hog 'em out). In the mid 80's (yep, 35 years go) my brother owned a '47 Ford pickup that he planned on restoring. Normally, 8BA inlet and exhaust valves are both 1.5 inches in diameter. Cylinder Head, Aluminum, Bare, Ford, Flathead, Pair. Note that although used, the torque plate has already been removed. Made of 3/16 inch cork and rubber. Fortunately, a wide variety of adapters are available to mate the venerable motor to today's automatic and manual transmissions. Copper sandwich type head gasket, 14 Grade 8, 7/16 head studs, nuts and hard steel washers,Distributor drive shaft. Reputedly, they are cast with 10 percent higher nickel content, and the quality of the modern castings is a lot smoother with much less core shift. Although a great leap forward when it was originally introduced in 1932, by the '50s the aging motor could not stand up to the new generation of overhead-valve powerplants like the small-block Chevy. All flatheads overheat, then the blocks crack. Try to achieve a smooth trumpet mouth shape that blends into the passageway. Relieved blocks must have the reliefs filled to use Ardun heads. A perfect example of how incestuous the primordial automotive scene was during these early years is the fact one of the most revered hot rod parts for the flathead Ford was created by Zora Arkus-Duntov. On the street, flatheads are happy on today's crappy gas, because that's the only kind of gas there was back in the '30s. The heart and muscle of the traditional hot rod. For even more protection, install a crossflow radiator and increase coolant system pressure to 17-21 pounds. Crankshafts are cross drilled for oil pressure to rods, counterweightedand machined for oil seals, freshly reground. Dont forget to match this measurement to the inlet on the exhaust manifold. A few early examples displaced 1.5 liters, but the majority were 1.55-litre (1557cc) engines, dubbed a 1.6. This can be a tricky, two-man operation. Gemsa was a champion Sprint car driver in the '40s and '50s, built and raced cars in NASCAR, and was one of the best at pulling performance out of four-bangers with his single- and dual-overhead cam conversions. Heads arrive complete and ready to install.Views show head complete with water pump choices (original Cragar type onright cast goose neck and thermostat on left).It comes with 8 tappets, 8 push rods and distributor drive shaft. Its easy to see what a gnarly casting the flathead typically is just by looking inside the exhaust port. The exhaust gas up-and-over maneuver, coupled with a hot reach-around the cylinder gave heat plenty of time to work its way into the engine. At the other extreme are dry-lakes, Bonneville, and nostalgia drag racers who have applied modern technology to the point where in some instances it is questionable whether the engine still remains a true flathead: Once-85hp engines now produce over 400 hp on gas and have exceeded 700 hp on fuel-all this on an engine with only three main bearings. The Melling M-15 high-volume pump is identifiable by the tall cap on the upper end of the shaft. Starting in July 1938, the blocks went to 24 head-retention studs. In essence, it was blueprinted. This improves airflow, but the resultant effective combustion-chamber-volume increase lowers the compression ratio, in turn decreasing horsepower and fuel economy. Water jacket holes are fitted with a copper ringlet. On a load of nitro, this engine made 320 horsepower and ran 229.77 mph in the Hill-Davis City of Burbank streamliner in 1952, breaking a record held since the 30s by Germanys Auto Union. It was a statement, in effect saying, "I am not a cookie-cutter rod.". Model B overhead valve side cover cast of premium aluminum alloy, also available for engine blocks equipped with flat head type cylinder heads. The pistons were balanced carefully; you can see the machining marks just inside the skirt. The process is the same as described previously. Scat H-beam high-tensile chrome-moly connecting rods with 2-inch crank journals match the old offset-ground crank. This engine produced 145 horsepower and 225 pound-feet of torque. You want to talk about traditional hot rods? Flatheads are old, ancient, obsolete technology. At that moment he also began saving money to buy parts for his first hot rod. Now, the intake gasket is positioned on block and the shape of the intake ports in the gasket is transferred to the block with a scriber. A set of H&H billet steel mains caps were used instead of the stock caps. Flathead Six In response to the post looking for Speed Parts for a Flathead Six. The exhaust valves do not have a reduced stem because they experience extreme temperatures. FORD 1933/35 FLATHEAD 21 STUD ALUMINUM HEAD 40-6050 RIGHT - MINT!! If the combination is properly tailored to the blower application, you should have no real problem. And there are always billet caps and girdles available. Because of the way the flathead was designed, the two inside exhaust ports thread through the middle of the block and heat it up before they are siamesed into one rather than two exit ports. For the overhead valve engines using covers that cover the old exhaust/intake ports. Keep it under 8.0:1. Mahindra 2816 HST, Super M farmall, J5 bombardier, 230 timber jack skidder. The first-design '32 through early '38 engines had only 21 cylinder-head studs and until mid 1936 even used poured babbit main bearings. Rc12Yc or the RN12YC a lift of.410 liked this article: feel...
