/6 and the B/RB

Problem is not the chain, or crank sprocket, they are the same as the big block. It is the cam sprocket that is different. I'm not sure just what the difference is. I think it is in the alignment. I have heard of several instances of BB sprockets being modified to fit the slant, to be able to use gear drive, or adjustable timing cam sprocket. I have never looked into it, as I have a few Cloyes double roller sets, and the JP and Rollmaster sets are available.
