Depends how much $$$ you want to spend and you goals. A decent h/c setup should see 430-450+rwhp n/a a 150-200 shot would suffice. However on a stock bottom end many say ~550rwhp is about the limit or you'll be on borrowed time. Forged is a different matter though. A for sure a built 408ci will make a decent amount more power.
