Meth or E85 Flex sensor
So question is I'm looking to buy a C7 and Procharge it. Question is should I do a meth kit or just do E85? And what is the max boost I can turn it up to without popping my engine haha

You probably wont have enough fuel to be boosted and run E85. You need 20-30% more volume and the stock fuel system just can't get you there when you're supercharged. Your best bet will be meth. Do the Alky kit and the D1 and you'll have a fast car on your hands.
Most can run about 9psi with meth and be more on the safe side. Some run more, but 9 is about the sweet spot. I run 8.5 psi with cam, headers, meth, and lt4 hpfp and make 705

I would think that on a 416 block you'd get even more benefit from heads as compared to a stock bottom. Is this not really the case?
