318 Cam Maybe Not

That's why I'm concerned about throwing a cam in and have it perform worse than the stock cam. Wasted money possibly.

As long as you don't go too big especially if you don't want to mess with a converter and/or rear gear change. If you don't need to disassemble far enough to replace a timing chain and it runs ok now, you might want to just leave it the way it is.
