Last season we could only run cams that would pull 15 in vaccum at 1000 rpm. This year we can either pull 15 in vaccum or run any can as long as lift isn't over 480. I have been running cam that is 244/244 and .510 lift on 112 to pull vaccum. Would I be better of with cam that is 248/248 and .475 lift on 106? Which is better more duration or lift. Running 4412 carb and max rpm about 7000 rpm
