He has plenty left after coasting from the 1100' mark for all the F,G and still H cars now even at 322hp. Might need a better reaction though. That's what happens when you show that kinda performance. You bring extra gaskets.

Looks like stock bore is 3.920 and MAX bore is 4.000. Thats .080 over and Diamond makes an approved piston for it, not to mention it is a +18 cc dome piston. Seems pretty easy other than you need a couple dead bodies in the trunk to make weight lol Also he only went 60 to 80 under last year. I think the engine really likes the bigger, lighter, better ring package, pistons.....just saying
