That is what it reads off the cam card, It's an exspensive cam but I'll let it go for $100.00 plus shipping.

Crane cams online has the cruise RPMs for efficent highway driving for their cams. You can match the RPM band you want to cruise in with your transmission and rearend ratios. Its at least an Idea

We put a ZZ4 cam with 1.6 rockers in a 383 Vortec engine we recently built. It pulls like a freight train well past 5K.
Kinda hard to believe that the ZZ4 cam has more lift and duration than the LS6 engine in the Z06, huh?
