i was looking at those and they look ok. but the exhaust has less lift than the intake. i know the exhaust has considerably more duration but i just dont know. also i wish comp cams would show the IVO, IVC, EVO, and, EVC @.050 soo i could see what kind of ramp rate they have. i am looking at the 35-602-8 the "big mutha thumper" cam.
her are the specs i found
