That's really as far as I wanted to go with a stock bottom end LT1
To run 13psi, I had a forged bottom end installed, then added meth for safety and a dual in tank system to make 864.
To get that beyond 15psi (~900rwhp), we'd need larger injectors and a bigger HPFP or a plate system to keep it fueled. Also, more ribs to prevent slipping.

Wouldn't it be cheaper to sell the SS and just buy a ZL1?
