I am looking to build a cheap motor, 5.3 heads and a small cam. I looking to see if i could use some of the stock parts for now so it saves me money. Are these parts worth taken a chance with.

stock lifters
stock main bolts
stock head bolts
stock rockers
stock crank pulley
stock 28lb injectors

also whats the stock ls1 intake good for, power wise

 

anyone help me

can these parts hold up to say a 400 rwhp car

stock lifters
stock main bolts
stock head bolts
stock rockers
stock crank pulley
stock 28lb injectors

 

changing cams your going to want to change lifters so they break in together besides that i would think your fine
