Overheating issues with remanufactured 360

So how are you going to break in the cam? You won't be able to run it long enough to do so because of the overheating issue, and you won't be able to run it to find the overheating issue in fear of wiping out the cam.

I'm confused.

Just take the top hose off and run the garden hose in the radiator. If the thermostat is good should be good. If the t-stat is bad...do over.
