Cooling Issue

the water pump pulley is #3462825

Thanks, I typed the wrong one.

What alternator are you using? Reason I ask is that right now I have an old single field w/ dual groove pulley. I'm using the rear groove now, but if I ran a shallower pulley like that 3462825, I'll have to move up the alternator a bit. Wondering how yours is set-up. Thanks.
