I've rebuilt 2 F motors so far. I bored them both out .30 over, that makes very little difference in terms of performance other than making the bore true and the rings to fit good. An RV cam will make it a little more peppy but don't plan on doing too many burn outs . An HEI distributor will give you a good strong spark and a little bit of pep but they're also pretty pricey.

A good carb rebuild and a set of headers will give you the most improvement, mostly in terms of throttle response.
