Since this is an 8, what is the difference between the 6 and the 8 vein? I was planning on buying the Mr. Gasket brand gasket with it. EDIT: I found the 8 vein Severe Duty unit: http://www.napaonline.com/Catalog/CatalogItemDetail.aspx/Water-Pump-Remfd/_/R-WP_58457H_0131329320 I contacted NAPA and they can not purchase this unit. (Why is it on their web sight?) Thanks

I've never had an issue with any cheap parts house rebuilt WP. I'd get an 8 blader if you can as it flows more & weld an anticav plate on it (6 or 8 vane) & you can also press the vanes closer till they are ~.030" from the pump housing for a more efficient pump then weld the vanes at the center shaft so the vanes will stay put. Support the front shaft at the cross when pressing the vanes in your shop press. Not everybody agrees but imnho the faster the water speed the better as long as pump speed ain't over ~5800 RPM (with cav plate) when picking pulley sizes which means a lower RPM eng can use a smaller WP pulley. EDIT set the gasket on the t cover then flip it over & it'll fit either way but 1 way it covers more flat area, it's subtle but you'll see

I bought the NAPA HP unit and it is #43026P and it is a new pump assembly, not a rebuilt unit. You can see in the picture the new one is a 8 vein and my old one is a 6. NAPA said that the 8 vein is the AC unit. Thanks

""Unlike Most Standard Pumps, Performance Pumps Are Less Prone To Cavitations For Longer Service Life."" This is from the NAPA websight for this new pump. Could they have done something to the pump to fight the cavitation issues? Thanks

Milodon has pumps made for them, but they weld an anti cavitation plate. AND they check and adjust the depth of the impeller. They said they find impellers at the wrong depth, that's why they check and adjust them.
Like this? Don't see anything about the plate.

I run that Milodon pump and it has a plate. Maybe Milodon's website mentions the plate.
