This welded and ground cam provides .308" lift at the cam, which works out to .320" lift with the stock rockers. For open modified applications.
The 308 is our most popular grind for modified clone class. This cam is easy on the valve train and has a very wide power band. This cam requires an upgraded spring package, billet rod, and billet flywheel. If using with OEM style stock Clone rockers arms, we recommend using the DJ-1070CM16 push rods. These push rods are shorter and will drop the rocker angle down on the push rod side and allow the rocker to achieve full lift.
Also fits the Habor Freight "Hemi" Predator212cc, Ducar 212cc and Tillotson 212cc. May require head modifications to the spring pocket area to prevent coil bind.

I am very happy with the results.
I have used this cam for over a year now and ever since I put it in my motor I have been up front in every race. This cam Produces a lot of power coming out of corners and it has yet to let me down.
