. . .Gradual heating up at Freeway speeds would indicate that the radiator is plugged up - suggest looking in YP for a Radiator Repair Shop!!! Also, the MoPar 440 engine REQUIRES a BALANCED SLEEVE Thermostat & WILL Run Hot if you install a REVERSE POPPET Thermostat!!! Robertshaw is the ONLY Mfg. of the Balanced Sleeve Thermostat. . . If your air cleaner is intact you will see a decal on the air cleaner stating this!!!!!!!!!!!!!
