okay, im running ross forged -6cc pistons (stock is -7cc), eagle forged rods, stock crank, and 4 bolt main, comp xe 230/236, and ported stock lt1 heads. I was going to run 200 shot of nitrous, but now im thinking turbo setup, how much boost you think i could run with custom tuning and 93 octane? im guessing compression is somewhere between 10.5 and 11:1 right now.
