Is this the right water pump for an L31 Vortec with Vintage AC?

I may have misread your original post. The one in your link on the first post is a reverse rotation. Either will mount up and the pulley will turn as normal but the vanes in the reverse pump are different. All gen 1 350s flow the same direction but a serpentine belt turns the pump in the opposite direction. To keep the water flowing in the right direction the vanes are reversed in a reverse pump. Just make sure you don't have a reverse rotation pump and some type of a bypass. As long as it doesn't have a cutoff switch in the line the heater can serve as the bypass
I apologize if I mislead you in my earlier post. I thought you were saying the pump in your link was the pump on the motor.
