I have a 1991 mustang 302 with stock cam and 1.7 roller rockers and want to put a e303 camshaft in it. With their be any problems with piston to valve clearance. I know the b303 with fit but i want to put in the biggest cam possible without changing the heads or pistons.

I run an e-cam with stock heads (self ported), stock valves and springs, and 1.7 RRs. It's a basic upgrade over stock and you will have no issues with clearance...but when I do it all again, I will be going with 1.6 RRs and a better cam.
