The block is already coated with Dykem. 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. Meanwhile, the outer two exhaust passages snake around the outer cylinders and make sharp doglegs before exiting the block. The benefits alone are enough for some, but the French comes at a price, both monetary and aesthetic. Tech help for our customers and Old School Customer Service! It will use a new oil pan and special bolt-on universal bellhousing that accepts most modern transmissions. Reserve these early blocks for collector cars due to their inferior head-retention and bearing design; speed equipment availability for them is also severely limited. You can now build a brand-new flathead. These headers have a 3/8 header plate mounting flange with 1 5/8 primary tubes to a collector outlet of 1 7/8 inch. "Joe taught me how to build these four-bangers to make them go fast," he says. Before he was 17, Joe had already ported and relieved more than 50 Ford flathead blocks for the finest engine builders of the day. The heads were marketed as putting 175 hp to a stock flathead with 250 horsepower on a bored and stroked racing engine. Back in the old days, all cars used low-pressure cooling systems, so coolant often boiled. Traditionalists can go with Vertex or Mallory mags, while modern guys may want to move up to MSD or Mallory electronic distributors. 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. To begin the porting process, Dykem was brushed onto the exhaust flange. This meant that the two inner cylinders would need to share a port while the outer bores would enjoy their own. They have a room completely devoted to the flathead Ford. About | Contact | Terms | Privacy, FORD FLATHEAD ENGINES: HOW TO REBUILD & MODIFY. Roller rocker arm with polley lock, needle bearing trunion and roller tip. The porting process followed here took an experienced machinist about 10 hours to complete.

The worlds quickest flathead dragster, Ron Schnells Slider, has run the quarter in 7.695 seconds; its blown flattie dynod at 939 hp on a 60-percent nitro load. In fact, the growing flathead movement has basically sorted itself out into three distinct groups. The clearance between the valve and the head needs to be at least .050 inch. Note that although used, the torque plate has already been removed. It was amazing to watch him.". "Everything he built was about going fast. This measurement is critical for a high performance engine. The old-timers took what they had and made it work. 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. Now it's 2005, and the flathead's resurgence shows no sign of diminishing. Ross, Wiseco, Egge, Arias, and others make pistons in any configuration you desire. Wear protective goggles and even a facemask to keep detritus out of your eyes, nose, and mouth. Required caps for installing Model A crankshaft in T block. So, despite its humble beginnings and inadequate provenance, the flathead can be made to perform. French blocks are about 30 pounds heavier than a standard flathead, which is a good indication of better metal and thicker walls. This can be a tricky, two-man operation.

The process is the same as described previously. Flathead History Lesson courtesy of Charlie Clark. Also, dont be too aggressive and cut through the port divider. Relieved blocks must have the reliefs filled to use Ardun heads. Grade 8 nuts and washers. Centerforce offers clutches and flywheels. Making power with a flathead is a fine balancing act, juggling the higher thermodynamic potential of raising compression against improving airflow through the combustion chamber. The numbers stamped into the combustion chamber identify each valve; they are lapped in and become port specific. 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. 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. Car guys (and gals) race things. However, thats only the start. Several ways of improving the performance through modifications to the gearbox and transmission train were . Not all of the intake bolt holes have corresponding holes in the block. The Ford Sidevalve is a side valve (flathead engine) . Not all intakes have this feature. However, the main caps are beefier than traditional stock flatheads. 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 passages are oddly shaped, with some right-angled turns, with all sorts of nasty casting flaws. Coolant needs to remain in liquid form when it circulates through the motor. Correct-length flathead 1.800 intake/1.600 exhaust valves are available from flathead specialists like Baron Racing. Fortunately, a wide variety of adapters are available to mate the venerable motor to today's automatic and manual transmissions. There was even a set of Ardun heads designed for the smaller V8-60 flathead Ford engine as well. For this group-whether building a rat rod, yanking a Chevy that just doesn't look right in that old Deuce, or building a brand-new car-the outlook couldn't be rosier, even better than the flathead's heyday so long as the bucks hold out. Because of the work on the head, the compression ratio was expected to be about 9.5:1. Reliefs between the valves and bores are much less pronounced than the old days, only about 0.080-inch deep instead of the old-school 31/416 inch. Tony Baron says that a good-running flathead should have no less than 0.400 lift and about 250 degrees duration at 0.050-inch tappet lift. Incidentally, the compressed thickness of the head gasket is approximately .055 (.060 uncompressed), and the stock Ford valve lift is .292 inch. 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. The heart and muscle of the traditional hot rod. Tony Baron says French blocks can be bored 0.250-over (1/4 inch). 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. 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 . One solution is adopting a small-block Chevy damper. Flatheads are old, ancient, obsolete technology. Gasket for original Miller/Cragar cast-iron cylinder heads.

Headers are also available with the flange plate to connect to the new Cragar cross flow head with blocked off intake ports and the extra bolt holes at each end of the plate. Some fuel-injection setups even run distributorless coil-ignition setups. The exhaust valves do not have a reduced stem because they experience extreme temperatures. Back in the day, four-barrel carbs had barely been invented. Speedway Motors offers pumps with sealed bearings that do an even better job in both early and late configurations. "At the end of the refrigerator car he had a small lathe," Max Sr. says. Consequently, Mike went through his stash until he found a near-perfect block. Don Hampton, at the age of 13, began working at a service station his father owned in Bell, California, a suburb of Los Angeles. A sophisticated gear drive system would morph into belt-driven camshafts in later versions of the Davies OHV conversions. 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. Box 53296 Albuquerque, NM 87153 Model B overhead valve side cover cast of premium aluminum alloy, also available for engine blocks equipped with flat head type cylinder heads. 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. Also note that the water pump is O-ring sealed. 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.

Longer gears enable the M-15 to pump 25 percent more oil than the stock pump. Nevertheless, it still needed align boring, boring, new hardened valve seats, and a judicious amount of porting. Because of Henry Fords intractability, the flathead was compromised right from the get-go. 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. The inside of the block was painted with Glyptal red enamel insulating paint, which not only looks good but also promotes the return of oil to the pan. And in a sense, the flathead also begot HOT ROD Magazine, for this publication probably wouldn't exist if not for the flathead speed industry and the advertising dollars it spawned.

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. 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. That necessitates larger, hardened valve seats and commensurate work hogging out the block to accommodate them. When the flathead Ford came on the scene in 1932, its eight cylinders offered more power than the previous four- and six-cylinder engines, and originally, the engine focused on the truck and heavy-duty markets. 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. For reasons known only to the crazy French, flatheads were used in French Army trucks through the early '90s. When you are finished, wash the part thoroughly to clean away all the chips. "It will probably make over 200 hp-and it'll be capable of driving every day if you want," Max Sr. says.

Our valve train is also unique to this head only, with needle bearing and roller tip rocker arms, 2:1 ratio, stud mounted. It will come with the clutch throw-out shaft and fork, including a new pilot bearing. The carbs are the new Stromberg BIG97s, and each flows 250 cfm. It was a statement, in effect saying, "I am not a cookie-cutter rod.". 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. Not all flathead water pumps are created equal, though. 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. Crankshafts are cross drilled for oil pressure to rods, counterweightedand machined for oil seals, freshly reground.

Use a back-and-forth motion on the stick, and reposition the valve every so often. 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. You must still do a physical check to ensure against a miscalculation and to make sure that the valves dont hit the heads. Over head valve and flat head type tube headers. Machining required to fit Model A or B cranks. 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. Flathead Myths courtesy of Tony Baron Flatheads may not have the cubes or brute airflow potential of many of today's modern mills, but there is a solution: Bolt on a supercharger. Part Number: DAC-15415. The measurement helps determine how much material must be removed to get the chambers back to size and to make sure that the valves dont hit the heads. Copper sandwich-type head gaskets with 4.060 inch bores. NASCAR and TV personality Ray Evernham now owns it. 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. Of course, this modern stuff requires a 12-volt electrical system. Most in this group will accept a modified flathead as long as it is period-correct, with no obvious modern technology visible. 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. Be sure that you do not let the tool get away from you and score the manifold. The first-design '32 through early '38 engines had only 21 cylinder-head studs and until mid 1936 even used poured babbit main bearings. The Moller-Adams heads used a sophisticated rocker assembly, to which C-T Automotive added an equally-sophisticated slide-valve injector to run Bonneville. I tried looking up ford 4 cylinder flat heads but don't find much. 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. Written by Greg Kolasa and Posted with Permission of CarTechBooks. And there are always billet caps and girdles available. A dial gauge was used to check the exact size and roundness of the bore, from top to bottom. 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. Stay tuned for further updates on this project. Most flattie builders modify factory pans. Zora would soon find employment at Chevrolet, after penning his famous memo about the youth market and their passion for hot-rodding the Ford engine. The cam has a duration of .302 and a lift of .410. Before the heads are finally installed, a dial gauge is used to ascertain TDC, using cylinder number-1 (passenger-side, front). Starting in July 1938, the blocks went to 24 head-retention studs. 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 . Whether planes, trains, motorcycles, or automobiles, Andy has immersed himself in a world driven by internal combustion. What's right for your engine differs per application. Clem TeBow and Don Clark at C-T Automotive had their hand in making the Ardun heads more favorable to hot rodders, but they also joined with Rudy Moller and Kenny Adams who built these more complex OHV conversion heads for the flatty. 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. Make sure the crank turns freely. Set comes with parting line and machined bolt holes ready to babbitt and fit T block. Traditional flathead airflow management practices call for relieving the block-removing metal between the valve-seat sides closest to the cylinder bore. However, Rays engine has 1.6-inch exhaust valves and whopping 1.75-inch inlets. The present-day Arduns are CNC-machined using high-grade 356-T6 aluminum, have refined combustion chambers, and improved oiling and valvetrain components. One of the biggest issues with the flathead was the exhaust ports weaving around the cylinder walls to exit on the opposite side of the engine. If you dont have Dykem, permanent marker works well. According to Mike, something with a good rebuild similar to Theresa Spurlocks engine (see Chapter 9), Navarro heads and intake, an 8.25:1 compression ratio, and a pair of Stromberg 97s should produce around 160 hp.
