Thanks Paul!

These stats are high flow (wide mouth);

Is a high flow thermostat necessary if I put the smaller pulley on?  Do you know which family of Mopar V8?  Thanks again.

Are you getting a hi-flow thermostat. As once stated a Mopar V8 is the same diameter.

I got my new water pump pulley today and it LOOKS like it will work.  I will post back.  I figure that pulley and a 180* thermostat will get me in better shape.  

TRUE.

The by-pass was engineered into the equation for a reason.

Restricting the bypass hose puts extra pressure on the heater core and its hoses and is of no real benefit. A word to the wise...Been there, tried that.

Along with the CASCO PUMP and PARAGON SPACER (not needed w CASCO PUMP) is another little detail. This casting defect will affect both the BIRD and PASS CAR.

The sedans cannot use the CASCO pump and no spacer on a sedan.

Paul,
I think most realize this.
What is being discussed in the VOLUTE OPENING in the FRONT TIMING COVER. Did you read the TECH ARTICLE?

Thanks DryLakes,

I ordered what I think is the right smaller pulley.  Mine is also around 7.5"...new one should be 5.82" according to CJ Ponyparts, or whatever it is.  

I had a '55 Fairlane with a 272 in Phoenix valley almost 20 years ago and never had any cooling issues.  That's why I was so surprised now.  I'll keep an eye on it and play around.  

When you say you block off that bypass between the pump and the thermostat housing, do you just put a piece of all thread or something in there and clamp it down?  

Thanks again.

There is more that just adding the plug with the 1/8 inch hole.  The thermostat must be modified too.

I found this out when I did the plug thing to my 56 TBird. With the plug in, when the car starts to warm up it gets really hot - nearly pegged the gauge  - got me very nervous - while the temp went down when the stat opened, it is not a good feeling when the gauge is pegged.  Not wanting to pull the stat, I took the plug out.
