The 1997 5.7 Vortec DOES NOT have reverse cooling. Reverse cooling is used on the LT1, LS1, LS6, 5.3 Vortec, 6.0 Vortec. Like I said in my previous post, an older style water pump will work.
Sly, I used a 5.7 Vortec to build the 383 thats in my Nova. I just used the water pump, pulleys and brackets from the original engine and everything worked perfect. Of course I am running a carb set up, if your keeping the TBI your intake coolant passages may be different.

BUMPSTICK You stated that you didn't believe a regular rotation water pump would fit. It will. That is what I was referring to. The Vortec engine I built the 383 out of didn't have the original water pump on it so I don't know if it was a reverse rotation.
