I had a solid roller 308 (.040 over) in my old siver car and it was a screamer. I don't have the cam specs on hand, but it managed to run on pump gas just fine with no detonation. Keep in mind, you pay for the raped ape performance of a solid roller cam with the constant checking/ajusting of valve lash and not being able to just idle your car infinately due to the stiff valvesprings. IMHO, I am not a big fan of the stroker motors. I dig the fast revving short rod motors that don't chew themselves up and can actually rev very high. I think they are just more fun in a light car.
