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. At one end there are restorers who insist on putting everything back to exact original condition. This measurement is critical for a high performance engine. 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. (Right) The flathead gets its name because the head is basically a "flat" piece of metal that covers the cylinders and valves contained in the block. 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. 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.

Several schools of thought exist regarding how to build a hot flathead, and the contention begins with the block. 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. Note that although used, the torque plate has already been removed. After the machining, grinding, and polishing were complete, the block is washed thoroughly in the hot tank and dried off. With modern flatheads routinely putting out 250-300 lb-ft of torque, the original trannies obviously aren't up to the job. During the engine's first decade of production, when overhead-valve engines were used by only a small minority of makes, it was usually . However, most of the casting flaws can be smoothed out. Back in the old days, all cars used low-pressure cooling systems, so coolant often boiled. This head has many improvements over the previous head. Click the button below and we will send you an exclusive deal on this book. You may lose as much as 30 hp above 4,500 rpm.

After all the machining, the intake was bolted down. 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 . Because of the work on the head, the compression ratio was expected to be about 9.5:1. At that moment he also began saving money to buy parts for his first hot rod. It was a statement, in effect saying, "I am not a cookie-cutter rod.". Of course, this modern stuff requires a 12-volt electrical system. A sophisticated gear drive system would morph into belt-driven camshafts in later versions of the Davies OHV conversions. The addition of a 4-inch stroker crank and another Stromberg 97 can push output up to almost 200 hp. The old-timers took what they had and made it work. A performance-limited bottom end and larger, more easily modified overhead-valve variants soon took the lead on performance. These include the '39-'53 Mercury and '46-'53 Ford castings.
