A friend told me about this " Tech Tip" from the Summit Racing Catalog page
85. So I thought I would pass it on to you all and see what you think .
Could this possibly help our hot running Tigers? Regards Armand Ritchie
Little Holes, Cooler Car
Our tech department handed us a letter from Mark Rael of Santa Fe, New
Mexico. It seems like-well, we'll let him tell you.
"After installing and underdrive pulley set on my dodge 440, I started
experiencing a hot engine when I slowed down in traffic. I tried all the
usual things: more water/less coolant, a flow cooler water pump, and even a
new radiator. Nothing worked. I wasn't overheating, but I was running too
hot for comfort.
I was going to try and electric fan when I called you Tech people, In
the course of the conversation, your Tech guy mentioned drilling a few 1/8"
holes in the flat border area of the thermostat to allow coolant
circulation before the thermostat "officially" opened. I had an extra
thermostat lying around, so I tried the idea. Needless to say, It worked.
Funny that a five-minute modification on a three dollar part was all it
took. None of the books I have or prople I talked to had a clue about such
a simple thing. Thanks to that sharp tech, I have a cooler running car."
