wouldn't go much past 13:1, the gains start to diminish past that point. as long as your tune is spot on, you wont have to worry about detonation

You could do 14:1. How fast are you tryig to go. Because in the realm of 14:1 and 434 cubes you looking at high 800hp on motor alone.

Good luck with that... a 351 block will snap just as easy as a 302 block with that sort of power.
