I have Comps version in a smallblock that just came off the Dyno. It sounds great and the numbers look good. Looking at my cam card the part number is 12-673-4. The cam card has a misprint on the lash so if you buy this one don't go with .012/.012... It wouldn't idle at those settings. Comps techs said it should have been .018/.020 . It idles at 1000 RPM now. Hope your not running power brakes though... No vacuum with this cam.
