I will agree. Although I am not disappointed with the performance of the E4, i'm sure somebody could grind me up one with a little more pep. But the way I drive it, a extra 20 horse wouldn't make much difference. I didn't build it for maximum performance just a nice driver and that it is. I also believe that crazy cam, regardless of how far you mess with it, it won't come close to a milder cam for your combo.
