Over Heat Problems

[Jaybear888]

hi there, I am running out of options to fix my over heat problem . Any ideas would be appreciate. I recently has a machine shop completely rebuilt the engine. Replacing new water pump, new thermostat, new heater core, new fan shroud, new radiator cap. Remove radiator ( 3 rows copper ) to clean by the shop . Currently has a five blades fan which is old but in good condition. Am I missing anything else.... thanks.......

What oversize was it bored to? If it is .040 over there's good chance to run hot. Is your ignition timing correct ? Some times a retarted spark timing will cause overheating. Also the bottom radiator hose should have a spring inside to keep it from colapsing or kinking.

One of the headgaskets is on wrong. You have to line up the water jacket hole. Normaly one gasket is shine side up and one shine side down
