With such a small difference; it's relatively easy to take a little off the Ford snout then slightly hone the inside of a Chevy balancer so it slips over the Ford crank. It was there one of the flatty's Achille's Heels was realized. 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. It wasnt long before hot rodders founded a market for overhead conversions of the flathead Ford engine in the name of performance gains. The third-design "8BA" '49-'53 engines have a bolt-on bellhousing, the distributor was moved to the top-right of the engine, and modern insert-style bearings are used on both the mains and rods. 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. The Chevy's crank diameter is only 0.060-inch smaller than the flathead's. As mentioned, the Ardun heads are likely the most popular, and for good reason. Youll pay a price for that too, though. This adaptor will except any GM transmission bolt pattern, like the Richmond, Muncie four speeds or the T-5 five speed. A few early examples displaced 1.5 liters, but the majority were 1.55-litre (1557cc) engines, dubbed a 1.6. The distributor here is the original Mallory dual-point. The Ford flathead wasn't the first V8 engine to come out of Detroit (that would be Cadillac's 1915 effort), but when it arrived for 1932 it was certainly the most affordable, sparking off a power revolution under the hood of American cars that continues to this day. You need the right amount of plenum volume and runner length to complement the engine size, camshaft, cylinder-head flow, and operating range. The object of the lapping exercise is to get the middle of the valve to match the middle of the seat perfectly. Lot #63,287. Taking the 119.5 cubic inch (2.0 liter) flathead four from its new 9N tractor, which was essentially half of the 239 inch Mercury V8, Ford offered this engine in half-, three-quarter, and one-ton trucks. 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. It offers adapter kits to mate GM automatic transmissions and Ford C4 automatics to '49-'53 8BA blocks, as well as a variety of adapters to mate both early and late flatheads to most GM and Ford manual transmissions. Starting with a 1949-1953 (or 1954 in Canada) 8BA foundation, the plan involves building an authentic high-performance engine of the era, with a big, 304ci displacement (3.1875-inch bore x 4.250 . (7) Actual Engine Displacement 2.3L/140 (11) 2.0L/121 (7) 2.0L/122 (4) 2.5L/153 (2) 1.9L/116 (1) However, the main caps are beefier than traditional stock flatheads. Traditionalists can go with Vertex or Mallory mags, while modern guys may want to move up to MSD or Mallory electronic distributors. FORD 1933/35 FLATHEAD 21 STUD ALUMINUM HEAD 40-6050 RIGHT - MINT!! Guys who once dreamed of owning a flattie back in the '50s but who had neither the time nor the money were now in their 50s, with lots of disposable income. 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. Not all flathead water pumps are created equal, though. Bob Drake has created a special category for parts that bring life to the words Flatheads Forever. A set of H&H billet steel mains caps were used instead of the stock caps. It has 7:1 compression, uses long reach 14mm spark plugs, like the Champion RC12YC or the RN12YC. 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. Unfortunately, old-school resistance to this "new and improved" part is so extensive that the SCTA has banned the blocks from competing in classic land speed racing classes. Buckler Cars manufactured 1172 Formula racing cars using a space frame chassis and the 4 cylinder English Ford Sidevalve engine and other Buckler sporting cars using similar . It was not your Dad's engine-it was your grandfather's. Not a bad place to start. You should have already decided if you plan to run one or not. Its not a good idea to experiment on the good block you intend to use because you could make a mistake and end up worse than before you started. There are several techniques; the accompanying photos show the method preferred by Baron Racing. Edelbrock, Wilcap (Sharp), and Offenhauser continue to market a wide variety of intakes. Not all of the intake bolt holes have corresponding holes in the block. Joe Gemsa was one of them. The new old cars got a lot of attention. That might involve time and disappointment as blocks are rejected. The old cam grinders-including Isky, Schneider, Elgin, and others-have both old and new cam grinds. Theyve been massaged by a long list of capable speed-merchants to great success and thanks to their resurgence in popularity, they are still available for anyone with enough coin to purchase a set. Most builders convert the stock oil system to a full-flow design with a modern, remote-mounted oil filter. 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. Riley Two-Port Company Cylinder heads for four-cylinder 1928-1934 Fords Charlie Yapp 570-A Rock Road East Dundee, IL 60118 (847) 428-6626 Roadrunner Engineering Supercharger kits, and Joe Abbin's book "Blown Flathead", which is loaded with information on both normally-aspirated and blown flatheads. Wilcap also sells '32-'48 Ford mechanical-clutch hardware. Tech help for our customers and Old School Customer Service! Fortunately, a wide variety of adapters are available to mate the venerable motor to today's automatic and manual transmissions. This gives you sufficiently accurate timing to start the engine. "It will probably make over 200 hp-and it'll be capable of driving every day if you want," Max Sr. says. Speed-O-Motive still advertises Merc crank cores if you want to go this route, but it's no longer necessary, what with all the aftermarket alternatives available. 2010-2016 Ford Miami Coyote V8 based Ford . Meanwhile, the outer two exhaust passages snake around the outer cylinders and make sharp doglegs before exiting the block. However, it is 114 inches taller than the stock pump, so more pan clearance is necessary. The valve assemblies were inserted into the block along with the C-clips. It is also produced with a 9/16 inch thick deck. This block is completely beefed up, with four-bolt caps, reinforced bottom-end and webbing, furnace-brazed sleeves (max bore is 3.5 inches), and new-design head studs that tie into the bottom of the block. Looking at the exhaust ports, youll notice the Alexander design still makes the exhaust ports do double-duty between two cylinders. It is easy to see that one of the ports (top) has very little extra metal to grind, so you must compromise. Because of the work on the head, the compression ratio was expected to be about 9.5:1. Grade 8 nuts and washers. The porting process followed here took an experienced machinist about 10 hours to complete. As seen by the scribed line on the lower left port, due to core shift in the casting process, very little block remains on which the gasket can purchase if all the metal is ground away. An alternative are Pertronix conversion kits that fit inside the original distributor; they retain the classic look, and versions are even offered that function on 6-volt power. For improved cooling efficiency, original '49-'53 pumps have more impeller vanes than earlier models. This engine produced 145 horsepower and 225 pound-feet of torque. The stock flathead oiling system is marginal for performance use. Another depth-measuring gauge is used to determine valve lift; it measures the distance between the top of the deck and the face of the valve, which in this case is .410 inch. Its never going to be a small-block Chevy, but it is a great little engine. But with modern solid cams and big stroker cranks, overall engine rpm and piston speed is considerably higher than the old stockers. It is running test-stand headers, not the final headers. 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. Note that although used, the torque plate has already been removed. Let's talk about four-bangers. 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. All rights reserved. However, Rays engine has 1.6-inch exhaust valves and whopping 1.75-inch inlets. 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. 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. Baron also offers a modern version of the famous Tattersfield/Baron four-carb race intake in more civilized street form. Bolts are being dropped into the corner holes to align the gasket properly. Be sure that you do not let the tool get away from you and score the manifold. From its debut in 1932 to the end of its U.S. production life in 1953, the flathead Ford underwent three major evolutionary changes. That was his entire shop. 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). There was also a V8-60-sized version of the Ardun conversion which moved both valves into the head on a hemispherical combustion chamber. There are over 50 different flathead intake manifolds, but they aren't all created equal. The baffl e has been cut out, and the pan is thoroughly cleaned of sludge. 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. 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. Water jacket holes are fitted with a copper ringlet. This stress relieving is important when building a high-performance engine. Most stock flatheads never came with an effective harmonic damper. And guess who taught Max Sr. how to build engines? Nevertheless, the flathead is the little engine that could. An OHV conversion shortened this path significantly. I tried looking up ford 4 cylinder flat heads but don't find much. He had a drill press, his work table, a tiny mill, and a welder. Stromberg in England is producing new Strombergs again. Tube headers for the Miller/Cragar overhead valve cylinder head for Model A 1928-1931 and 1932-1934 chassis. The carbs are the new Stromberg BIG97s, and each flows 250 cfm. hurry up or it will have no stock. $1,399.98. Before the heads are finally installed, a dial gauge is used to ascertain TDC, using cylinder number-1 (passenger-side, front). 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. Others prefer an original 8BA. But that just leaves these pristine virgin blocks for us normal street guys. Gasket for original Miller/Cragar cast-iron cylinder heads. While exact ignition timing will vary per combination, in general flatheads running gasoline like about 23 degrees total advance normally aspirated and just 19 degrees with a blower. Flatheads began to come back, and prices of swap-meet stuff skyrocketed. Copper sandwich type head gasket, 14 Grade 8, 7/16 head studs, nuts and hard steel washers,Distributor drive shaft. Our valve train is also unique to this head only, with needle bearing and roller tip rocker arms, 2:1 ratio, stud mounted. As its name implies, Red's Headers is the place to go for the widest selection of street-style headers. Crankshafts are cross drilled for oil pressure to rods, counterweightedand machined for oil seals, freshly reground. At one end there are restorers who insist on putting everything back to exact original condition. 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 engine is destined for the historic Woody Lee T, raced in the late 1940s and early 1950s; it reached a top speed of 133.136 mph at Bonneville in 1951. One solution is adopting a small-block Chevy damper. This is not the truck pan with the inspection plate. Machining required to fit Model A or B cranks. To begin the porting process, Dykem was brushed onto the exhaust flange. Part Number: OFY-1069-425. Part Number: ARP-154-4104. Magnuson offers an Eaton blower kit, while Joe Abbin of Roadrunner Engineering has Weiand 142 and 174 supercharger setups. 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.
