Re: Bbc pulleys?

69-72 Chevelles have the long water pump. So to keep the truck setup you will need a short water pump. The pulleys and brackets from a 66-68 Big Block Chevelle will work. Crank, water pump, power steering bracket/pump/resevoir and alternator.

FYI, this will be a significant expense if you were hoping to do a cheap big block swap. A lot of people keep the long water pump pulleys and brackets, but I prefer spending the money for the short pump setup.

Re: Bbc pulleys?

All trucks '72 and earlier came from the factory with short water pumps. That's what I prefer to run in the '72 and earlier trucks. Then you can run '68-'72 truck big block components or '65-'68 car big block components.

You might want to look into this setup from kwik performance, they make a really nice kit for the bbc . This is from my build thread, they use sbc SERP mounts and fit is awesome, I’m very happy with it.
