I'm not sure why this post was removed yesterday so I'll try it again.
I've got a GM (stewart) short water pump off of a mid 80s Corvette. I'd like to use it on a 67 331 I've built. I realize that the original setup on the Vette used serpentine belts and the pump spun opposite the direction it will turn using a v-belt and the 68 Z pulleys I've adapted to it. I thought this wouldn't work well until I pulled the back off of the pump and looked at the impeller. It has a stamped steel impeller with straight vanes, not curved vanes like the cast iron impellers I'm used to seeing. Since the vanes are perfectly straight I would think it would matter which direction the pump was turned. Has anyone else tried this?
Thanks for any input,
