Alternator Relocation to avoid frame rail

The pulley did not line up with the water pump pulley. I did my best to measure the offset and came up with 0.48 - 0.54. I currently have the damper removed so was only able to put a straight edge across the water pump pulley. Somewhere in the back of my mind, I remember the difference between the early blocks, and the VVT blocks being .545. But I'm not 100% sure that is the number.

Holley's documentation shows .48" difference.
