Mopar R1 block

The CRA in the beginning of the part number, C stands for conventional nose, D would stand for Dwell nose, as used in stock eliminator racing.
R stands for lobes suited for higher rpm design.
A stands for asymmetrical cam, opening and closing ramps different, which usually have a slower closing rate to eliminate valve bounce.
Roger that, I should have looked a little harder, a local cam grinder here has quite a few crane profiles and it sure looked like one,almost an exact match to one a buddy had from the part number down to the timing specs. Do you know if it's an older ultradyne profile?, just curious since I have not seen that one in the master list but I believe the one I use has updated/newer lobes. At any rate it should get the job done!.
