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

That would be one nasty cam. The exhaust having less lift than the intake wouldn't be a detriment. You should be able to contact Comp Cams and get those figures you want.

so you dont think the exhaust being less would be a prob uh. thats kinda what i was thinking. i was figuring on running 1.7 rockers with this also to get a little extra lift. but its all just thinking at this point. i also like the extreme energy cams and the nos cams. i know eagle is running one. what do you think of it eagle??
