New water pump 6 impellers whats up with that!

From the factory A/C cars used pumps with 8 blades and non A/C used 6 blades. At least that is what my original factory Mopar parts manual shows.

Not true. The AC cars ran 6 blade pumps from the factory and the non-AC cars ran the 8 blade pumps.

I run a FlowKooler water pump on my car. Has a plate welded on the impellers to prevent cavitation.
