I had the problem of not having the right pulleys. for my 8 bolt water pump. the engine I bought had a 69 balancer with 8" 3 groove pulley. the water pump pulley was a 6", 2 3/8 deep. I originally put a 7/8 spacer behind the pulley to bring it out, but then the mechanical seal went out on the water pump. I thought here was my chance I went and bought a 11 bolt timing cover and water pump. Installed it everything going great until I went to put the water pump pulley on.

NOW it's off by a 1/2 the other way (not deep enough). The water pump is just shy of 4 1/2".

Does anyone know what I need for a pulley? the one I have is 481040XT.

It's a real mess to figure out.

This link might help.

For myself I wanted the 11bolt pump but still use the old brackets for the PS and Alt. It took a lot of research to figure out.

It sounds like you might still be trying to use the small balancer with the 11 bolt pump.

Read the links they should have all the info you need.

Do you have a/c and p/s?

To make sure that the fun never ends, they made 2 sizes 11 bolt pumps. The early '69, the short snout, and the '69.5 and up the long snout.

I have a pdf that lists all of the pulley options/part numbers for 1967-69. give me your email and I'll send it to you.

I seem to remember downloading it from The First Gen Site, but now I can't locate it.

I have the damper and pulley for 69 and later but I have the long snout pump for like a 72 and later big car. The car has power steering, no a/c. The water pump has a (72) stamped in it.

I had a 69 and later damper, crank pulley, and apparently an early (2 3/8" inch deep) water pump pulley. Do any cars with the later (longer) pumps have a 6" water pump pulley?
