318 Cam Maybe Not
- You don't need a cam change, it will work fine, although there are better choices than the stock cam. be sure to include a new timing chain.
- Hope your 302 heads aren't cracked, if they are, nothin' wrong with working with the heads that were on there.
- follow that 4bbl with a good dual exhaust system
Forgot to mention, engine still has stock cast manifolds but after that it has 2" dual exhaust with low restriction mufflers.
