Andy: could you supply a part number for this cam? "Comp Cams 264/268 solid roller with HXL and HXX lobes" Thanks Birdtracker
It is a custom cam. If you want to duplicate it just ask for 264/268 with HXL and HXX lobes. You'll also need to pick a lobe center.
My suggestion to birdtracker is to contact Dwayne Porter (fast68plymouth) for the cam, especially since he may have a different recommendation for lobes, depending upon the application.
