I never got any numbers out of mine before I pulled the motor for my TSP 370 that will go in over the winter, but I was running 8psi on a T70 stock long block (other than springs and pushrods) while we played with it. Saw 12psi a couple times and never had any issue. We were being very safe with timing and fuel tho, thats obviously the key! Go for it!

My buddy made 500rwhp/500ft-lbs at 8.5-8.75psi with a 78mm turbo on an STS kit. Bone stock motor. Only thing they changed was to a 918 valve-spring and pushrods cause the stock springs were letting the valves float.
That was through a Ford AOD trans(no lock-up) and a 12-bolt.

Sell the ls1 longblock, buy two 5.3 longblocks and you have a spare. Throw in a z06 cam/springs/pushrods, and let it eat. Should be good 550rwhp or less for quite a while. Mine is just over 550rwhp through an auto and has been taking a hard beating this year in my car and maxxmitchell's car before mine, 140k mile junkyard longblock.
The biggest hands down way to make it survive is a GOOD tune.
