They were very similar, but the E8 cam had 10 more degrees of duration for the intake valves (276 vs. 266). Obviously, that meant that the intake opening and closing points were different, as was the overlap. The lobe lift for both cams was the same for intake and exhaust (.278"). The less-aggressive "soft" lobe profile on the E8 cam, which was done to reduce valvetrain noise, reduced horsepower by about 3 hp.

That is some great info  You will never feel 3hp on the butt dyno but it is still good to know. Where do you find this information? If you don't mind me asking.
