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.

Allen 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 do think the Source pump is junk and causing the overheating problem. If it still runs hot with a decent pump, then it's the clutch on the clutch fan. My

I can tell you that the source pump and stock are 2 completely different animals as far as construction and design.

Went to a local cruise night. it was a nice and cool 65 degree night and its still running hot. The car was running great, 170-190..then after about 15 minutes into the drive it will get up to 210-215. Im not sure why its doing this... The temp is not dropping down while cruizing.. In my case, the source pump was NOT the problem. Now could the housing be a problem? I flushed the block a bunch when i built the motor, and flushed it recently again. Im going to try a 160 stat and see what happens.....

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. Ron

Ron 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?
