Sorry, guys! I didn't think it would make that much difference... figured they would be ok or not.
I would be building this engine to take 20psi. O-ring the block. The actual HP number is of no consequence. If the research is correct, 20psi out of a moderate 292 should be in the 800HP range. In a 65 Nova, that's ludicrous! Not a race car. But will be raced.
