Rebuilt motor with forge internals but used factory crank cause I heard they were a beast. Was this a good idea? More importantly; Also new rebuilt motor has only 40 miles on it. Been trying to break the engine in but motor is overheating. I never let the gauge get into the red but all the water is boiling out of the overflow first. I changed the thermostat (I could see it was broken when removed). But that didn't fix the problem, unless the brand new one broke too?, hadnt checked that yet. It wll idle all day and never get hot. Both radiator fans come on like they are supposed to and I can see the water circulating. Then I go for a ride and it gets hot. Is it just the friction from the new engine or something? I've been breaking it in but not ever going past 5k RPM, running it but not killing it. New oil looks great, no water. My project cant progress until I fix this and I'm pulling my hair out. This happen to anyone else
