Small block 350 with a short water pump, in 1972 Camaro with low mounted P/S pump on the driver side and high mounted alternator on the passenger side. Need pictures of the pulley arangement because I'm having trouble with belt placement. I have a new three groove pulley on the crank, but the top two groove pulley was scavenged from the junk yard.

Dont have any pic,
however I'v seen this prob before. On an S10; 350 engine, short water pump I had. If yours is like mine was( in too far)simple fix, I used some 3/8 washers to shim the water pump pully out(shims go between water pump and pully). I think I had to use 3 washers per bolt hole to get mine lined up right. Also I used some gasker sealer to hold washers in place.
Hay it worked. Hope this helps
