To me, it kinda depends where you would be at, compression wise, without milling. 7.8 to 1, sure, .mill the crap out of em, 10 to 1, uh, no. 11 1/2, gonna run on E85, okay.

470 stroker, It's 11.4:1 to 12.02:1 this will be a dedicated drag car & using the correct fuel.
Which isn't determined yet 110-116 octane
