None of the stock pistons are suited for boost. The top ring lands break by looking at them.

To consider the fact that a heads/cam/headers/ported intake 6.1 (stock shortblock) can go low 11's to high 10's in a 4000 lb race weight IRS car with all the proper mods, stick it in a 3000-3500lb classic mopar with a chassis you can actually tune and its gonna be quick !



I wish I still had my 6.1 for my Roadrunner

For a stupid fast car, I would run a forged 6.1, 09 5.7 heads worked up by someone who knows them, a 3.6 Kenne Bell and be done. 1200HP @ 20ish PSI with EFI taking care of the rest. It could be done for about $15,000 with the blower (no efi yet) if you shop carefully....
