stock block and internals
 

how much hp can the stock internals hold up to? im guessing im around 260 right now and im getting the heads ported and a 100 shot of nos i dont no where ill be from there maybe 380? im thinking of gettin forged internals first tho im not sure someone help a brotha out!!

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 :(

I wouldn't push it past 400rwhp.
