Feel like 360 should have more power

That would probably set it on fire compared to what it is now. That or maybe something like a 252-260 range. That's about as much as I would go.
A comp 252 is basically a stone stock 360-2bbl cam
Duration and overlap are pretty much "dead nuts" identical. Comp has 15-thou more lift, that's it.
I've used them in 318s before with a noticeable improvement, stock idle but butt dyno sure feels improvement. AKA melling spd25
