Re: Comp XR286
I run the XR 282hr and I was told its a "Austratempered" material, not steel billet but better than cast. I was also told to use the factory stock steel type gear, no brass, maybe consider the Poly gear . I started out with the 986 spring but went to AFR heads with 1.550 dual springs, running about 140# closed . One thing I did do was run a MSD dist with their gear and it ate my flat tappet cam , thats why I run the roller now. The gear is cut too sharp on edges, I am told by CC. If you compare the stock gear teeth and MSD gear , you will see no bevel on the tooth. Need to have that bevel and it comes with all factory gears from GM.
