I have some more information involving small block pulley sets. First the crank pulley centerline dimensions using the harmonic balancer face as "0".
#3850838 first groove .305" second .925"
#3858533 deep groove .370" second 1.125"
The water pump pulley measurements using the first groove centerline of the C/S pulleys to the pulley mounting surface.
#3890419 A/C pulley 2.330"
#3770245 deep groove 2.400"
The related pulley groove centerlines, alternator, P/S and A/C would be in the same relative location to the crank. My issue is the .135" (.065" + .070") difference between the '608 W/P and the '326 L79 W/P flange locations. Assuming of course, the balancer faces are common between the two engines.
The water pumps have rebuild specifications of 5 9/16" and /or 5 11/16"; could that be the reason?
