Hello, I am new here , and have read some interesting things about the flathead Chrysler 265. Me, being an old drag racer always want to know , What will it do in the 1/4 mile? I have read every page of this thread and no one is mentioning weights, gear ratios, including rear end gear ratios, actual readings from a tach, or even oil pressure. I myself have been racing super stock Hemis and max wedge cars since 1972 and I am thinking on building a Chrysler Flathead 6 in a Willys body. I will be using all the same parts suppliers as I have used in the Hemis and max wedges. My machine shop is on red alert about this project. This will be my second Chrysler 6 in a Willys that I own. The first one is still together and ran a best of 14.50 @ 91 miles per hour. It weighed 2860 with me in it, had a 4.78 gear in the 52 Plymouth housing, a 38 Dodge 3 speed tranny, went through the finish line at 5200 rpm. It was wound out long before the finish line. The motor was 60 over with 3 ford 94's for carbs, on a stock manifold,( reworked ), 100 thou off the head, a reground cam which I have the blanks so that I can grind more, headers. Absolutely no off the shelf speed equipment was used on this motor. This combo gave us 60 class wins, I still have the trophies, and many cash awards. This car has been retired since 1968, and sits about 15 feet from this keyboard. The car was driven to the track until 1966 and then we used a tow bar. So my question is , how fast are the big boys going with their new style "Speed Parts", on their flatties?
