PKRWUD is Chris, and a B cam has significantly less lift than an E cam.
B303 .480/.480 224*/224*
E303 .498/.498 220*/220*
The B cam will pull harder up top because of additional duration, and a smaller LSA. The E cam will perform much better on auto cars, and below 3000rpms. The B cam is somewhat hindered by it's lack of LSA in regards to it's overall lift. With a set of 1.7's, it becomes a much stronger cam.
Last I checked, Skyler is looking to slap some 1.7's onto the E cam, which will push lift to about .530.
