has there been an agreement more or less for a stock type-high flow? it couldn't hurt to put one on my 68 396. in south texas it is often 95-100 degrees outside and along with factory air etc. it could use some help. thanks fellas.

I'd be interested on what the concensus is here, as well. I'm looking into swapping my short factory water pump to a long high flow pump. I was looking into a Procomp water pump.

Is this a good pump or a cheap POS to stay away from?

Bite the bullet and buy a Stewart pump, thats my thought on the matter.

I had an ebay aluminum water pump special and it got sent back after it was puking!!!!

Jack With similar conditions in NE Texas as you have there I gave a lot of thought to my cooling system. Read for months thru the threads looking for answers as I wanted to build it right the first time. Came to these conclusions.

Do not let $300 difference in price keep it from being right

We fired the new motor and let it "break in" for over 30 minutes at 1200-1400 rpms on a 90* day in my hot shop. It took about 15 minutes for it to get to 180* and never eased over it . The water flo and air being produced was amazing even at just above idle. I feel it will cool with great success when the car is completed.

Buy the Stewart you will be pleased.

Stewart's High Flo Pump will definately help you,along with there Hi-Flo thermostat BUT be warned...A Stage II Short Water Pump has modifications done to it and you can NOT use your stock pulleys. A Stage I is there completely stock mold and will replace your pump using your pulleys. Stewart will not tell you this tid bit over the phone. I've been there just 6 months ago and they wanted to replace my used Stage II for there stage I after I complained to there Tech Manager. That information was supposed to be posted in there Web site but never made it yet. So-If you want an easy R/R buy a Stage I. If you buy a Stage II be ready to buy new pulleys and belts. Personally-I really don't think there's any big difference anyway between the two. Good Luck

so which stewart? stage 1,2,3 or 4 are you guys thinking about?

Why not order a GM waterpump. Your car being a short pump car allows you the option of using a GM part# 14058915. Aluminum hi flow L88 pump. It managed to keep a L88 vet cool and being a GM part might be worth something a few years down the road.

P.S. If that doesn't cool it you have other problems.

stay away from the china junk, unless you feel like modifying brackets to get belts aligned. THe victor jr pump is nice for the price, but the gm pump mentioned above has always worked for me.

If you already have a SWP... I don't know why you would want to switch to a LWP.

For what the water pump does they work the same. The bypass hose fits better on a SWP and it provides a LOT more room for stuff in front. Like big electric fans :D

I went through a lot of work myself to swap the other way for just this reason.

im goin to have to switch from a short to a long myself... most serpentine setups with p/s only, require a long pump.
