Damn dude almost the same exact thing happened to me. I bought an engine from them and ran it for maybe 1000 miles and it threw a rod. I took it in and they said they would see what they could do. Couple days later they told me it was my fault but couldn't tell me why. I called bull crap on it and went in swinging. They re-built the motor free of labor charge but I still had to buy a re-build kit. I ll never ever go to them or have anything to do with them again.
