I have a 1966 Dart GT with a 273 4bbl engine. The engine has been refreshed with new rings, bearing and gaskets. Original pistons were used since there was very little wear in the cylinders. I did change the cam from original to a Comp Cam XE262. The engine has the LD4B intake and a Competition Series Carter 625CFM carb. I put on a new water pump, hoses and a new aluminum 2 row radiator. The radiator is from ebay and it is one that looks just like the original in appearance. I don't know how...
Over heating 66 Dart
