Default what are stock bottom end ls3/l92's making

im gettin very close to the finish line of my turbo build. and now im wondering what the l76/l92 motor can handle safely( bottom end).... ive seen a couple new corvettes make in the 7XX's on cam only motors but i need some more input . should i keep it under 650 untill i put rods and pistons in?

my motor has
arp headstuds
stock gaskets with copper spray
double springs
pushrods
turbo cam

and its gonna be fed by a PT74 gts
im lookin to put about 7 to 9 psi on er!

it seems like 550-650 is a sweet spot, everyone i know pushing over 700 seems to break something after a while.

If you can't push 800 reliable then something is out of order
