I have a 350 that is bored 40 over with 9-7-1 forged pistons with dart cast heads with a 510 lift cam and victor jr intake with a holley carb. I have about 350 to the wheels and I want more power. I was thinking aluminum heads and with a bigger solidcam or nitrous with a 150 or a 200 shot. I need your oppinions

 

Considering you have forged pistons, I would definitley go with nitrous oxide. Not only will you get the most bang for the buck,but it's probably one of the easiest things to do for more ponies. The only things you need to worry about are: What compression ratio are you running? High compression engines tend not to last long on nitrous, also is your cam a dual pattern with a longer exhaust duration? If those things are in check, grab you a bottle!

 

yeah, nitrous, but from how you describe the build, I am a little surprised your not building more power
