I'm looking at buying a '98 Z28 that currently has a Vortech supercharger on it (not sure of the model off the top of my head) running 6psi. He says he has everything to bump it up to 8psi (I'm guessing it's just a pulley and a belt?) but hasn't done so yet. My question is if I buy this car what am I going to want to do to the bottom end to safely run 8psi? I know all kinds of good stuff about rebuilding a top end, but have never torn into a bottom end before. Are forged pistons and hardened pushrods basically the only essentials? Any info would be appreciated. I've tried searching but it doesn't come up with too much. Now I'm going to go back to religiously reading all the previous threads in this forum

Thanks in advance
