Actually, low rpm and idle quality should be good. With that shitty 216* intake duration and 112LSA it should make for good vacuum and decent low end.

I will never understand why somebody would go with that cam though. Piece of **** in my opinion. I don't see the need for the exhuast to be that favored, and quite frankly, you're always making sacrifices.

In this case the guys at comp cams have people believing they have a great cam by going to insane lifts with small durations and favoring the exhuast side so they can keep up with the word of the day. In actuality, lifting that valve up like that is killing hp left and right that you would have with a longer duration lower lift cam, and it's hard as hell on the valvetrain. I'm suprised it doesn't bend pushrods like an LS1. The profile on that cam has got to be crazy steep putting a ton of pressure on the pushrod as it has to lift on a near vertical surface. Throw into the mix you have to run an expensive high quality valvetrain or wreck pushrods, rockers, and springs. Oh well, it's the Crane 2030 "miracle cam" of the day
