350 runs hot...need help
I just put in a new 4-core radiator and a higher flow thermostat in my truck. Idleing it hovers just below 230. If I punch the gas the temp drops. If I hold it at a constant RPM it heats up again. I havent driven it anywhere while it is hot like this. I have even put a furnace blower infront of the grill to blow more air. The shrould is on and the fan is moving a good amount of air. I have been running without a thermostat because I just figured I needed a bigger radiator. I have a year old Remanufactured water pump and new hoses. The motor is a '76 350, .060 over, Vortec heads, Elelbrock Performer Intake, and Comp Cams 252 High Energy camshaft.
The engine has done this since I put it in in early July, but I just took the thermostat out. I had a leaking head gasket problem earlier, but I seem to have gotten that fixed. Other than the temp, the engine is working good. A mechanic friend said to check and make sure I dont have the Intake gaskets on backwards. Thanks for any help, Mike |
