Which one flows better, factory 6 blade water pump or 8 blade

Then you're saying to the guy you MUST run a zillion groove ac pulley.
No thanks!
We are NOT restoring to stock, so that's irrelevant what pulley the factory used!
Johnny is just giving you a history lesson more or less.

Use the non a/c pulley, be it with or without power steering and the 8 blade pump. It works.

I'm only talking about the water pump pulley and water pumps. Never did I say anything about crank pulleys.

Fact:
AC cars: 6 blade water pump, small water pump pulley.
Non AC cars: 8 blade water pump, bigger water pump pulley.
Only 1 of my cars has AC. It has the 6 blade setup.
The non a.c. car has the 8 blade setup.
