All of Comp Cams have lobe numbers, the lobe numbers are in some of the older Comp Cams catalogs in the back. The Hi Tech roller lobes are a type of lobe in thier catalog. The numbers at the top of the cam card usually identify the grind number and the lobe numbers like CR3 4131B/4020B R 108.0. Look your ups and post it on this post and i will be glad to dig out one of my old Comp catalogs and furnish the lobe specs for you.
