Weak points of the LS1? I'm planning on getting an f1a procharger on 8psi soon, and I just wanted to know what were some weak points on the motor. Right now its all stock except for LT headers and ecutouts. I did some research and found the crank could go up to 900-1000. Also the valvetrain should be upgraded but I won't be revving to 6k and I'm leaving the stock cam for now. So do I need pistons, rods, head bolts, rod bolts, etc? I'm hoping for atleast 500whp.

The weakest point in the bottom end is the rod bolts. However, I spun a crank bearing and effed up the whole assembly. I would go ahead and get rods w/ARP 2000 bolts, Eagle 6.125 rods, get the blocked machined out .005'', and a piston built for bost to lower compression. That will make for a strong bottom end.
