Who makes reliable aluminum water pumps and housings?
There is so much junk out there sold by big name companies I don't want to end of with something that doesn't fit right or fail in 6 months

Thanks for any input

BB or SB?

70 440

The housing is a simple casting with no moving parts so hard to go wrong there. If I was buying a new one I'd probably get one from Mancini Racing just because I deal with those guys a lot.

The water pump is going to be a crap shoot. I usually prefer brand names on stuff like that but there is no guarantee that any pump will last a long time. I've had Edelbrock pumps fail quickly and I've had them last for years. Once again, I'd probably just buy a pump from Mancini on the theory that they sell a lot of them so they know which vendor is good and which isn't.

If you aren't super concerned with weight you can get cast iron water pumps really cheap from Summit.

I've seen cast aluminum from 60 to 350 so that's got me wondering 60 bucks there has to be something wrong there

I've used edelbrock, MP, and also a few 20 dollar parts store pumps and they all worked great.

I haven't found a housing that I like quite as much as the MP one which is no longer produced, or the stock iron ones.

don't know about electric....

Only $53 shipped to your door. They were $40 a few months ago.

the housings are pretty much all cast in the same place these days. check for casting flash inside and make sure all the opening are there. may have to grind the open to allow proper flow.

on the water pumps, I always run the mylodon high volume pump. been around forever works well. flow kooler makes another style of pump that supposed to work well. i'd stay away from any of the pumps with a cast impeller

Thanks everyone!

I've used a 440 source housing and pump on my car for the last 8 years without any issues.

Yep, mine has been on two different engines (blew up a 440, no fault of the wp) for well over 5700 miles and 4 years. Never any issues with the 440Source pump, housing or thermostat housing.

My MoPar RB housing had quite a bit of casting flash and raw machined edges in the water path, I blended them in for peace of mind. I was also not impressed with how far away the impeller blades were from the housing inner surface, milling a bit off the forward mating surface would make that closer but I never did.

In my exp w pumps are as dependable as any part I have ever dealt with. I would cut a disc in half & weld it behind the blades (on a BB pump) for an anticav plate & get a pump with the most vanes. What Poly said, you want the impeller to housing clearance as minimal as possible (.040") & for sure check/port/deburr the housing (as needed). & adequate pulley ratio

Good idea

Whats the diff in weight between the iron water pump and the alum one ? ... NOT talking about the housing. The last time I looked there was a H U G E price diff.

Not a huge difference on the pump, I think it is 2 or 3 lbs. The difference on the housing is much larger.

8 pound savings on the housing. Not even sure there is even a full pound difference on the pump itself.

Have bought all of mine from Mancini. Ron

Mancini ..the hi flow one with the anti cavitation plate

I also have the 440source one and a Mezeri water pump
