The only GM reverse rotation water pumps I have seen are the counter-clockwise units for serpentine belt systems.

Jim was able to hook up starter & place some tape on balancer, YES it does crank clockwise. It appears that the water pump may be off a marine engine as every "car" pump,he's looked at pictures for 389, the vanes go opposite to the one he removed & now can't figure out "why" it didn't overheat??? in the years he's been driving it. In the process of installing A/C & has has most of front engine stripped.
