Would I be able to run forced induction with my current set up on my 99' GMC. Would my cam work well? Would the cam work with nitrous?

 

That cam is mild enough not to lose too much bottom end. Even if you lost a little, nitrous and/or a s'charger would pick it right right back up. The 3000 rpm stall is even further insurance againt any low end bogginess. Ought to pull strongly. Enjoy..
