i had a stock 360 bottom end with forged repl pistons, Stock crank stock rods etc, In my car it ran 13.00 on motor and 10.90 with nitrous, It had two plates stacked for a two stage, both jetted at 175each so yea that was 350hp on a stock crank stock rod motor. Keep it out of detonation youll be surprised at what lives..Id keep it to 175 though and you should be ok. A 360 cast crank is pretty beefy
