The pump is made by Cat and is sold by many different people.
I have a NIB cat pump going onto a mild 451
I have a CAT housing and pump with a 160 t-stat and I can't even get it past 160 degrees with a stock 22" radiator w/clutch fan. My 440 has 12-1 compression and a .600 lift cam. I did drill out the head gasket's water holes that were slotted.. Not sure how much diff that made.

Most of my overheating problems went away as soon as I got rid of the underdrive crank pulley.

Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first.
Life was a little easier when I was just a wrench.

I'm curious to see what you guys find out. I just put on a 440 Source pump and housing on my new motor. I'm not quite done installing it. Hopefully I don't have this overheating problem!

Well the one fact that is indisputable is that MY engine ran cooler with the stock housing and Milodon pump. There was also much better circulation across the top of the rad with this setup vs the 440 source housing & pump. That's a FACT !
INMO, the housing is a problem, anything that restricts waterflow in & out can't be good for cooling. Coolant that languishes inside the block & heads too long is going to boil.

I hear you, and agree. Bummer 440challenger, can you or will you change out your Source housing to see if it cures your problem?
Isn't there guys here running the Source housing without overheating issues?

What kind of stat are you running?
Some have the big slots, others have the more common small passage.
I want my fair share
