Im in the process of freshening up a 400 out of my 78 Magnum. I have a question about how good the 440source aluminum water pump housings and water pumps are. I will be wanting the passenger side inlet housing. Any input would be great! Thanks Cam

I just hogged that passage out on the one I have as there's plenty of material in that area - it took all of ten minutes to do. Otherwise the casting is nice and fits fine. For the price you really can't beat it.

It is a High Volume but only at higher RPM, not at idle where I needed it on my Challenger Tom , 2011 Ram 3500 C&C Diesel 2009 Challenger R/T 1971 Challenger Conv. 511/4 speed 1970 Challenger R/T 503/727

Otherwise the OP really has no alternative choice if he wants something other than the stock iron housing .

I used a stock replacement pump and thermostat housing from Napa. It all bolted up nicely with no leaks. I run it on 100 degree days in traffic and stay at 180.

Also the casting height is different from the OE Mopar aluminum one, forces one to use different spacers to get the proper fan belt/pulley alignment. May work OK for a casual cruiser but dump it if one has built the motor and/or lives in a hot climate. Just my $0.02...

How hot does it get in the summertime in Indiana? We ran 1 for about a month on our 520 inch stroker, the temperature ran well about 210 degrees. Pulled it off, installed the Mopar OE water housing and temperature dropped 25 degrees.. We sold it for $25 @ last year's Spring Fling Just my $0.02..

I went balls out and got the real one from Mancini with the matching HV water pump Family owned 1969 Charger R/T DualQuad 440/727/GVO/3.55s

I decided to get the waterpump kit from mancini that they have made, came with the pump, housing, and chrome water neck for $140. The motor hasn't been ran yet, but the passages are good sized and I like the looks of it

Trashed the pump and installed a Milodon pump runs 185 all day now. Still a little hotter then it ran with stock houseing and stock pump. If i ever have to pull it apart again i'll hog out the pasages. They are half the size of OEM houseing.
