I ran both cams as well, but the B303 needs to be run with 1.7/1 rocker arms instead of the stock 1.6/1. The lift is quite a bit less than the E303 although the duration and overlap is more than the E303. Out of all the Ford racing cams the E303 is the only street "legal" and emission approved cams. Streetability on the E cam is better as the torque peaks at around 2500RPM..better for cruising than the 3300 peak of the B cam. Personally I'd prefer the E cam for all around driving..
