Your designing a rearmount turbo and keeping the stock bottom end is stupid ...the stock bottom end of an LT1 won't hold much boost and won't even hold low boost for long. What is ok for the stock bottom end will be terrible when you build the engine after the piston lands break.
I know I had a stock LT1 and 400 RWHP is pushing your luck but mine held until I put together a forged motor. Put 7-8 psi on a cammed LT1 and you are out of the range for any detonation--meaning you will break the ring lans if you have much of a cam.
How much power do you think the stock pistons in an LT1 can take? A friend made ~500 RWHP and it held until he made one mistake tuning and hit detonation...
Boost and stock pistons mix like oil and water
