Thread: Water Pump Question

Tweet

Looking for recommendations on high volume water pumps. This mildly build 454 will be run in a 55 Chevy for strip, not street, and will use the original radiator to start. But, even with aftermarket radiator, space, and volume is limited. Ideas? Thanks

Edelbrock Victor Series #8850, Weiand Team G #8243. Both are short style, aluminum, high volume. Should be plenty for a mild 454.

I have Stewart stage 2 pump, with a 185 stat it works great. The key here is the fan, you need to cool the rad at low speeds. i have a black plastic flexalite 90 degree fan. they move a ton of air.

Thanks, I looked for a flexalite 90 degree fan, but didn't see one. Where are they available?

i have used the stewart. victor .weiand .moroso low drag they all work good but the stewart is what i have now and it seam to work better than the team g and the moroso. with the way i have the water speed i have and the the shim in the top hose .your car has about the same size rad as my 50 chevy and i can at time keep the 548 blown engine cool. but is will get heat soak my gto has a alum pump not sure but i think it a vic and has a rad the same size as your car and will not get hot that and old gm 4 core but the engine is all alum but it is past 630+cid with a flex fan i did a 548 14to5 engine a 29 A bone with very small alum rad with a vick pump and did not get hot at all. more of it has to do with water speed and air getting in and out of the engine

Thanks, great advice. My old cast iron pump is a long version. Any difference between the long and short, other than just getting more room in the engine compartment? I guess a different crank pulley may be needed?

No and yes.

The long pumps may last longer because the bearings are spread out more to support the shaft better.
