i can change pistons if i need to since its not together yet....i already gotta take the crank in to be cut for a 2nd keyway. not sure if that will change the balance or not but if it dont then i was just trynna keep from buying new pistons and having to rebalance if i could make it work. ive read on yb of alot of guys running 6 psi with e85 and higher compression but just not sure if that goes for pontiacs too.
