I agree with the previous posts. You may want to replace the thermostat, hoses, and check the water pump if it has been running that hot! Our F2 is a 1977 and has the heavy duty orange 292 gas. Our F's have the same orange 292 engines with the older point system instead of the module. Both have been trouble free (knock on wood). We believe in maintainence though and constantly blow out the air cleaner, blow off the engine, and check hoses, linkages, governor, and adjust things accordingly. Make sure everything is tight and in good condition. The exhaust manifolds sometimes crack (we have replaced only 2). Other than this these engines I would recommend to anyone and I'm not a big G.M. fan either. What is the difference in the blue_orange 292 enginesIJ Just the yearsIJ Good luck, let us know how you make out!
