[DeTomaso] Overheating

[shawkins777 at comcast.net]

Did you put a new thermostat in and if so are you sure it's a Cleveland thermostat?

Hi Jack, I have a new Romac balancer installed on this new motor 
and the timing is set at 32 max with no vacuum advance hooked up. 
I read that my engine symptoms could be related to the gas getting too hot in the carb . 
After touching the carb and burning my finger I went out and got a half inch phenolic spacer. 
It didn't help much as the carb still got really hot after 15min of driving. 
After burning my hands on the inner fender I thought it might be a good idea to 
reach out to the forum for help :) Tonight I will try and burp the system again 
by raising the back end of the car. I'm running out of ideas.

Check your timing, especially the harmonic balancer orientation. The outer ring often moves relative to the hub, and if you then set ignition timing to that (shifted) mark, your ignition will be severely retarded... which overheats. Too much advance also overheats. A street 351-C only needs around 34 degrees ignition advance TOTAL from true Top Dead Center, including static, centrifugal and vacuum advances. All these are easily adjusted. 

I suspect you are also vapor-locking the carb because things are running hot. A carb isolator plate made of non-heat-conducting material (including wood) should help. Good luck- J Deryke
