Also one thing some of you are forgetting is the new cars running higher collant temps also run HIGHER SYSTEM pressure , I had to buy an upgrade kit for my rad pressure tester , it tests up to 30 psi now .
Higher system pressure raises the boiling point of water and helps prevent steam pockects.

I just pulled the source pump and housing in favor of a stock housing and milodon pump. Hasn't been hot enough to make a difference but I will report back.
... FINALLY!!! THE MYSTERY IS SOLVED!!! ....HATS off to Doug for the topic and NachoRT74 for that awesome link put a stock housing on and a milodon pump and it cruzed all day long in 90+ florida heat yesterday, stop and go, everywhere!!! The 440 housing I had, you could barly get your pinky into the 90 deg turn in the lower opening. I put that 440 housing and pump on my new motor 2 1/2 years ago and could'nt get the temp down but never suspected the housing because it was brand new..........

.....Yes new cars do run hotter but lets not forget the new motors are built to much better tolerences. New cars run 200,000 miles all the time. The 60's motors were worn out at 70 or 80 K on them.
Hmmmm. Bit of a simplification. Maybe the 4 or 5 speed overdrive lock up converters have a little something to do with it and their 2.0 final overall drive ratios.

there also computer controlled. Running a 60's motor runnung at todays engine temps would kill them in 30K miles.

Higher presure cap does not raise water temp. It raises boiling point.

I do not agree. I've never seen a 318 worn out at 70-80k miles, much less a /6. If they wore out it is simply because people did not take care of them

Still waiting for a detailed explanation of the above claim.

If you run a 440 at 220 degrees, it won't like it. New engines run even hotter than that at times IIRC.
I want my fair share
