Its possible if you come at it from an oblique angle. Be very conscious of this before you start grinding. Short of machining the block oversize for custom roller-cam bearings, even with a reduced base circle this limits max cam lift to about 0.460 inch. Every plug must be checked. Stromberg in England is producing new Strombergs again. Each of the 16 valves was hand-lapped using a small amount of fine-grade VersaChem metal grinding compound. NASCAR and TV personality Ray Evernham now owns it. Current custodian Evernham plans to race it again. The pistons were balanced carefully; you can see the machining marks just inside the skirt. Instead, air wants to go over the front of the valve and hit the chamber roof. The heart and muscle of the traditional hot rod. 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. Side-valve chamber gasket, .060 thick. And guess who taught Max Sr. how to build engines? The Ford flathead V8 (often called simply the Ford flathead, flathead Ford, or flatty when the context is implicit, such as in hot-rodding) is a V8 engine with a flat cylinder head designed by the Ford Motor Company and built by Ford and various licensees. The completed engine for Ray Evernhams Woody Lee T started on H&Hs test stand with the first turn of the key. A four-cylinder with an overhead conversion could be built to make cubic inches and horsepower that the V-8s had a hard time matching. Research has shown there's relatively little air movement over the base of the block. The new engines overpowered the old chassis, so modern suspensions and disc-brake swaps were added to the mix.

When the flathead Ford came on the scene in 1932, it's 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 '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.

A new player is Gemini Electronic Fuel Injection, a complete bolt-on flathead conversion kit based on the self-programming Prodigious fuel injection system. Honing the block of this high-performance flathead follows essentially the same procedure described previously, but in this case, the tolerances are much tighter. 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. When Ray acquired the car, it was still fitted with its 8BA flathead, but a few parts were missing. Consequently, a number of shims are required.

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. On Rays Navarro 3 x 2 manifold, Dykem was painted around the ports before the gasket was laid down. Youll pay a price for that too, though. This measurement determines the necessary depth of the valve pockets. Over head valve and flat head type tube headers. 1932-1972 Car and 1932-1979 Pick Up. Despite having three rather than five main bearings, the flathead has stayed the course. Many hard-core guys still swear by Isky's 400-JR solid (0.400 lift, 244-degrees at 0.050, 111-degree LSA). 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). Custom billets stretch all the way to 4.5-inch stroke. The stock 1.5-inch valve is to the left. of Heads in the late fourties into the early fifties. 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. One reason is the fact that a lot of development work had already been done, and a lot of speed equipment had already been created to make the four-bangers fast. 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. With modern flatheads routinely putting out 250-300 lb-ft of torque, the original trannies obviously aren't up to the job. Its easy to see what a gnarly casting the flathead typically is just by looking inside the exhaust port. Mahindra 2816 HST, Super M farmall, J5 bombardier, 230 timber jack skidder.

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? Hot rodders from every ilk soon found the Ardun heads beneficial for more than heat dissipation. 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.

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. A micrometer depth gauge is used to measure the depth of the combustion chamber. . Wear protective goggles and even a facemask to keep detritus out of your eyes, nose, and mouth. I now have remade it in a style that will allow the use of the 1932 B water pump. It has 7:1 compression, uses long reach 14mm spark plugs, like the Champion RC12YC or the RN12YC. 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. If it boils, steam pockets form, and when you have steam, you'll get cracks. In this image, a dot is visible on the ring just below the file; it indicates the top or uppermost side of the ring. This head has many improvements over the previous head. This encouraged the old-time flathead parts guys (or their sons) to start repopping the old parts. Add to Cart. 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.

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. The first-design '32 through early '38 engines had only 21 cylinder-head studs and until mid 1936 even used poured babbit main bearings.
