    How much power can stock LS1 block safely handle?

    Just curious what you guys are getting out of these cars now. What is the ceiling for these cars with stock blocks? With or without power adders.

    i think its good for a round 900-1000 but the internals are safe to only around 500-600. key word i think.
    your in the forced section so....i think you mean on boost. most only put 7-8psi on the motors and still say they are safe. that can put you in the 450-500rwhp range. wihch is 5-600 hp
