e303 or tfs stage1?

With either cam,you'll need to upgrade to Mass Air.I have an E303,and it loves the higher rpm's.I really like it.I can't speak for the TFS cam,I have never used one.Are you using the stock short block from the Cougar?If so,the pistons are really going to limit your cam options since stock pistons don't have valve reliefs.Swap in a new set of pistons,and then get crazy.
