OT: el camino pulley problem
 

I just traded my '70 GMC beater :whine: to my Dad for my Grandpa's '68 el Camino :cool: He had a guy rebuild the 327 a few years ago, and I think he mixed up the pulleys. It has power steering and a/c, so 2 groove water pump and 3 groove crank pulleys. Problem is, the water pump pulley sticks out about 1/4" too far, causing misalignment with the crank pulley and a rub with the ps belt. My first thought was maybe the guy put a corvette water pump on it, but it has the correct short pump. I found a part description in a chevelle catalog for the water pump pulley, and I think I have the right one. (6 1/4 dia. 2 11/16 rear space) So, I guess it is the balancer or crank pulley? The balancer is about 1 1/8
" thick. Any ideas? Does anyone make spacers? I tried washers, but pulley wasn't centered. Anybody got the pulley I need?

From what I have seen, the face of the balancers are all in the same location. There may be some exceptions but I have not seen them.

Is your power steering belt lined up with the crank pulley?

Also, is the crank pulley groove up tight against the balancer?

I just looked at my 65 SS Impala which has the small block engine in it with ac. I believe that it is the same setup as your El Camino. The water pump double pulley on the Impala has a 2 7/8" offset.

Ah Hah! That was my first thought after discovering that I have the correct pump, then I saw that catalog. I have seen some pulleys that are almost touching the boss on top of the pump, and I have about 1/4" gap on this one. Anybody have one of these pulleys for me?
