blocks handles 420, crank handles 600

Depending on mileage, i wouldn't go over 400-420HP to the wheels, some tuners told me 450.

if you have any plans to build the bottom end then do the right thing and do that before you run the nitrous. At least then you won't have to worry about it.

keep the shots at or below 100hp and you'll be otherwise normally ok. There's always the chance something will pop though so building it is the best way to go.

skip the head porting and NOS....just buy a blower. Itll be cheaper in the longrun.

usually most people keep it around 420-430rwhp.. but damn if you have the chance build it instead of blowing it up. dont make your car a ticking time bomb
