Simple question Do I have a long or short water pump? I have an 89 GTA with 5.7 . I want to replace the old one when I do rebuild.

 

You have a reverse-rotation, long water-pump.

 

Reverse rotation?? I don't see that listed in Jegs or Paw I will look again.Thanks.

 

I think the one reverse rotation the carry are aluminum Edelbrocks, but they're there

 

Just because Jegs, PAW or Summit don't list it, doesn't mean it's not available. They only list a small portion or their stock. It's best to just call and ask them.

Example. Look at all the cams they list for Crane or Comp then look in the Crane or Comp catalog. All those cams are also available from the mailorder houses but they won't list them all.

 

My mistake PAW has it listed. Thanks again

 

I've heard of JEG's and Summit but what's PAW? I tried www.paw.com and got some research site... what's the url for paw if it's another performane parts source? Thanks guys.

 

Does my 91 LO3 Camaro have the same? I have been wondering that for a while now. I don't think it is reverse flow though.

The serp belt spins the water pump backwards compaired to a V belt small block so your L03 should be reverse flow EROCK. Also they stopped using the short in the 60s (I think) exept for a few applications (read Vette). Please correct me if I'm wrong, Knowing me I am.

 

WHOA!!!!, LT-1s use reverse flow. we use standard flow.

 

standard flow, reverse rotation.

 

Thats what i meant. Told you i'd screw something up on that.

 

PAW stands for Performance Automotive Wholesale www.pawengineparts.com

 

I'm about to purchase a Meziere water pump for my '89 GTA and it lists it either with or without the heater and bypass ports; which one should I buy for my car? Thanks in advance.
