I have a 76 105 chrysler that has been converted over to a force. But like if i idel to long going down rocky river so i dont make a wake, or try slow trolling with it, the heat alarm goes off until i speed it up alittle. I have a new water pump kit and everything else new down there so i know the pump works.. Some people have told me that was normal of that engine. That it liked to get up and go!!! The headgasket is new, head block has been re-bored(how ever u spell it) New plugs and wires, carbs been cleaned and tuned. So does any one have a thought.
