Track Attack Hi-Ram: 14:1 minimum compression. Will require flycutting for adequate piston to valve clearance. Strong to 7600rpm with correct valvetrain setup and High Ram manifold.ġ3:1 compression minimum, ideally 14:1. Track tested and developed 9 second cam with heads and supporting mods. Very street able, requires 4500 plus converter. Track Attack: All out performance application. 040″ gaskets, and a Hi Ram Manifold, in a 6th Gen Camaro weighing about 3600lbs went 9.90s in the 1/4, and made over 590 RWHP!
