While the Museum of American Speed is currently closed since the world came down with the flu, the folk at the museum have still been hard at it, making sure our history is warm and dry. 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. Early and late distributor styles can be interchanged by using the corresponding front engine covers and cam drive. That necessitates larger, hardened valve seats and commensurate work hogging out the block to accommodate them. . Cylinder Head, Aluminum, Bare, Ford, Flathead, Pair. ", Gemsa built engines and parts in a 20-foot refrigerator car behind his house in El Monte, California. Let the chips fly (and they will) as you cut into the soft aluminum with a cutting tool. 1904-1906 Ford Model B (1904) engine; . Chrome-moly nuts were also used. "Everything he built was about going fast. Four carbs on a properly designed intake manifold offer the best distribution short of today's dry EFI systems.

Baron, Edelbrock, Sharp (Wilcap), Navarro, and Offenhauser make both old-style heads as well as improved new configurations. Custom billets stretch all the way to 4.5-inch stroke. The block has plenty of material in this region, so you dont have to worry about grinding away too much. In this image, a dot is visible on the ring just below the file; it indicates the top or uppermost side of the ring. Part Number: DAC-15415. Part Number: ARP-154-4104. These include the '39-'53 Mercury and '46-'53 Ford castings. Free shipping. Those valve covers would look right at home on the Indianapolis 500 speedway and doesn't look dated next to that Aurora IRL engine in the photo on the right! The pistons were balanced carefully; you can see the machining marks just inside the skirt. The clearance between the head and the block is only the thickness of the head gasket, therefore, pistons must not come up out of the cylinder bores more than .030,,,,,,,more than this and there could be piston to head contactThis must be fixed during engine assembly by checking and machining the piston tops down to the correct clearance. After the machining, grinding, and polishing were complete, the block is washed thoroughly in the hot tank and dried off. 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. Most flattie builders modify factory pans. The new 1.75-inch inlet (right) has a reduced stem diameter to improve flow. 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. In particular the area between cylinders 1 & 2 and cylinders 3 & 4 have been beef up with an internal rib about 1 inch tall to stiffen up the head. Traditional flathead airflow management practices call for relieving the block-removing metal between the valve-seat sides closest to the cylinder bore. With modern flatheads routinely putting out 250-300 lb-ft of torque, the original trannies obviously aren't up to the job. The second ring and top ring are installed next, in the same coiling manner. 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. Although new aftermarket iron blocks are reputedly under development, right now a real-world solution to finding a good core for your flathead is to start with a brand-new French block. After the intake ports were opened up, its time to machine a hole in the manifold for the road breather tube.

Between the two cylinder bores, you can just make out the exhaust passage through the three holes. There was even a set of Ardun heads designed for the smaller V8-60 flathead Ford engine as well. 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. There was a 226ci engine used in lots of cars over the years with a max power rating of . To begin the porting process, Dykem was brushed onto the exhaust flange. 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. For Rays engine, H&H chose an original 4-inch Merc stroker crank that had been offset-ground 1/8 inch. Download Instructions here. It used a Ford 116E iron cylinder block and a new aluminum cylinder head with dual overhead camshafts. Not all of the intake bolt holes have corresponding holes in the block. Two things to watch out for are an extra water hole in the block and the lack of a breather standpipe in the block. 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. The valve assemblies were inserted into the block along with the C-clips. 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. Lot #63,287. Solve cooling problems by using a modern water pump available through Speedway Motors and other sources. Model B overhead valve side cover cast of premium aluminum alloy, also available for engine blocks equipped with flat head type cylinder heads. Its easy to see what a gnarly casting the flathead typically is just by looking inside the exhaust port. It was a statement, in effect saying, "I am not a cookie-cutter rod.". Eventually you could build a whole street rod out of aftermarket commodity parts. On Rays Navarro 3 x 2 manifold, Dykem was painted around the ports before the gasket was laid down. When number-1 is at TDC, the pointer on the timing cover and the notch on the crank pulley (here marked in orange) will align. The process is the same as described previously. 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 . What's right for your engine differs per application. Cast from high quality 355-T6 aluminum alloy. 2023 Power Automedia.

However, Rays engine has 1.6-inch exhaust valves and whopping 1.75-inch inlets. 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). 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. This cool little track-nosed, turtle-deck T, known as the Woody Lee T, raced in the late 1940s and early 1950s, hitting a top speed of 133.136 mph at Bonneville in 1951.

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. 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. There's just a pulley on the engine, and he says it runs well. Crankshafts are cross drilled for oil pressure to rods, counterweightedand machined for oil seals, freshly reground. Finding value in style points, he can appreciate cars of all power and performance levels. 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. You can just see the valves in the plug holes so you know that the clearances are tight. As mentioned, the Ardun heads are likely the most popular, and for good reason. 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 carbs are the new Stromberg BIG97s, and each flows 250 cfm. 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. A high-pressure system will run fine with no boiling, even at 190-210-degree gauge temps. Tube headers for the Miller/Cragar overhead valve cylinder head for Model A 1928-1931 and 1932-1934 chassis. A flathead engine, also known as a sidevalve engine [1] [2] or valve-in-block engine is an internal combustion engine with its poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve engine . You must still do a physical check to ensure against a miscalculation and to make sure that the valves dont hit the heads. Andy has been intrigued by mechanical things all of his life and enjoys tinkering with cars of all makes and ages. 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. The valve pockets in the head are machined accordingly. New stainless valves are available from several sources. This d4b cylinder head is a copy of the Thomas flathead that I used to produce about 10 years ago. Note that, because it is a race engine, it has no generator and, therefore, a shorter belt was needed. With some exotic tuning, it has been known to produce 700 hp, and not just for short bursts. With the heavy-duty versions being most susceptible to heat issues, the first attempts at separating exhaust heat were designed for the truck market. Set comes with parting line and machined bolt holes ready to babbitt and fit T block. The fi nal bore is 3.3125 inches with the torque plate. Stromberg in England is producing new Strombergs again. 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. If all the calculations are correct, the engine will produce approximately 225 hp. Consequently, Mike went through his stash until he found a near-perfect block. He keeps his feet firmly grounded by working on his two street rods and his supercharged C4 Corvette. The addition of a 4-inch stroker crank and another Stromberg 97 can push output up to almost 200 hp. Spiral locks are little fl at springs that you pull apart and ease into the groove in the piston. Now it's 2005, and the flathead's resurgence shows no sign of diminishing. Head accepts long reach RC-12-YC or. 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. 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. There is also an ugly governor mounting boss on the left-rear of the block that many rodders prefer to machine off. This head has many improvements over the previous head.

", Among this herd of sheep, a few original hot rods were brought out of retirement, complete with gennie flatheads as the powerplant. 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 clearance between the valve and the head needs to be at least .050 inch. The heads were marketed as putting 175 hp to a stock flathead with 250 horsepower on a bored and stroked racing engine. Roller rocker arm with polley lock, needle bearing trunion and roller tip. A pair of these heads appeared at Indy in the Bob Estes Special in 51, having been run the previous year with an Ardun flathead. The two ports immediately to either side are siamesed, and the gases exit to the bottom through the exhaust port. Back in the old days, all cars used low-pressure cooling systems, so coolant often boiled. (Photo by Tim Sutton). With so much spring pressure, you must be careful not to trap a finger. This stress relieving is important when building a high-performance engine. Wilcap also sells '32-'48 Ford mechanical-clutch hardware. Then, about 20 years ago, traditional street rods suddenly became cool again. The aim of the honing process is a nice crosshatch finish that performs superbly. High-compression is the way to go. That changed eventually, but a few rodders never lost their devotion to 'bangers. This improves airflow, but the resultant effective combustion-chamber-volume increase lowers the compression ratio, in turn decreasing horsepower and fuel economy. The passages are oddly shaped, with some right-angled turns, with all sorts of nasty casting flaws. And, if were lucky, we may just get a glimpse of an over-head conversion in the process! French blocks are hybrids, essentially a '49-'53 8BA in terms of deck height and front-end, but with the integral cast bellhousing and corresponding oil pan as found on the '38 1/2-'48 59A. Dont forget to match this measurement to the inlet on the exhaust manifold. Coolant needs to remain in liquid form when it circulates through the motor. 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. 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. Research has shown there's relatively little air movement over the base of the block. 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. 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. sidebar view as Show Sort by Add to cart Dual Core Radiator; 1939 Deluxe, 1940 Car, 1940-41 Pickup $859.99 Speed shops began working the heads for more flow and performance and soon, you found them competing in every form of competition.

While we have no evidence that he actually said those words, his summation of their desire could very well be true for the day. 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. The best balance has been the subject of debate for over 60 years. He had a drill press, his work table, a tiny mill, and a welder. This same gasket can be used on engines with flathead-type cylinder heads by cutting the top part away. Some say that the NOS French block is the way to go, and in some ways it is. 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. Others prefer an original 8BA. There was nothing slow about anything he ever fired up. Even stock flatheads can run 6-7 psi boost with no problem. This is not the truck pan with the inspection plate. When the Stromberg BIG97s arrived, Mike used the included gasket to see if the top of the intake would also have to be opened up to match the big carbs. Made of 3/16 inch cork and rubber.
