Well here is what I found. The lobe just before the second journal sticks past the journal by a few .000 so when the lobe is in the bearing it raises up the cam so the journal doesn't line up with the bearing. Does anyone know of a supplier of cams for this motor? Would it be better to have the journals turned down on the other cam that I have or start over with the other engine I have from 55 and just use the 53 block for a anchor. Could I sand the lobe down to fit?
