Re: Camshafts
Ford made 3 different 5-brg. cams. First all 5 brgs. were finish-ground to the same size to match the blocks being used. 2nd series #2 & 4 were finish-ground to a smaller diameter to make installation quicker and easier, blocks were now 3 bearing. 3rd series were merely rough-machined because it was cheaper to do so. The lobes were all the same. Value? All the same.
