Would like to get a little more HP out of my stock engine, am I waisting my time trying to get 425 Hp or should I build a 400 engine, mine has chevy 3x2 set up so not matching. With a set of pontiac carbs what all should be done and at what cost, as you can tell I am not a wrench. THANKS
 
depends on your budget, install a set of Edelbrock aluminum heads and a a different cam and headers will get you close to your HP number
