How much hp would I make if I make 330 stock
How much torque would I make if I have 400 n/a
If it’s not compatible with the L31 engine, how come it says L31 vortec heads in the description? I would like to know if it will work with a stock 5.7 vortec out of a GMC Sierra Z71. Also, what would be the minimum I would have to do for this to fit.
