John, In dealing with all of the RAT motors that chev builds we have found that if the timing is off a littli bit it will cause an overheating problem. you didn't say what type of fan clutch you had ie viscous or air. you definitly did the right thing in replaceing the temp gauge with a stewart warner unit. all the 366,427,454 and such operate at a much higher temp than the fords or chryslers. Keep trucking, PM
Perry, thanks for your suggestion. I am new to fan clutches and really don't know how to know whether I have a viscous or air clutch. I am going to tune the engine and see how that effects the temp. It has been running well, yet I am sure a good tune could only help. Thanks again!
