P-V8,

You are certainly correct about piston speed. If the math is correct, with a 5 inch stroke and 11 inch long connecting rod, 1.2:1 rod ratio, this engine is at 1450 feet/second @ 3750. This actually seems kind of low for such a long stroke. Fortunately, the Egge pistons I installed utilize modern Hastings rings, replacing the double one-piece oil control ring with one multi-piece oil control ring.

As far as the endurance test and flat out speed run for 1939, they were definitely two different runs, about 4 years apart. I have never heard top speed cited in the endurance run. Conversely, I have never heard how many miles the 1939 top-speed run was. O_D will probably be the best person to answer this question. I am in no way trying to discredit either of these marketing demonstrations, but do believe there were some deviations from standard equipment (i.e. gearing).

Pat,

I am totally intrigued by the work done to your engine. I would love to have a high compression head! You really have some fantastic sounding modifications. I think you and Turbopackman have horsepower at heart. Sounds like with the modifications your engine has, you are probably generating a good bit more torque and horsepower than my engine. Again, I really appreciate the information you have provided. It is most unusual for an early 320 to be used in daily service, no less in a professional car. Good for you!
