1965 corvette water pump pulley

[John S.]

What are the dimensions for the correct water pump pulley for a 327 365 hp hi-performance 1965 corvette? What are the widths of the deep grooves? What is the OD? This is a L76 with no air.

Here's the one you're describing; The P&A catalog says 7_1/8" OD. I'll get the other dimensions in a few hours, as it's uninstalled, in my basement.

Wayne, Did the SHP pulleys have that backup washer shown in the picture? It's been so long since I put mine on I can't remember if it was there.

No John, I don't believe the reinforcement #3720616 was ever TFP for '65 or prior C2. Maybe used in '66 or '67+ due to high belt loads on the water pump with certain options. I know there's bulletins out on this.

Here's the other two shots of the '245'. As the forward groove is added by pressing on to the rear groove / cone, there is only one groove looking at the inside.
