November was 12 months. Not forsure miles on motor i did drive truck before i pulled motor. Reason i got this motor was i spun a bearing on my motor. I asked around all said might of damaged crank. Instead of messing with my motor i used other. Yes i did get to see motor a part. don't know what to look for he said it needs rings wrist pin and something with the cam. He showed me the cylinder walls there a groove up at the top of cylinder he said valves looked good. So i a looking at $40 for taking a part motor $175 rings, hone cylinder walls and install. $130 for install and part for cam. $40 for resurface flywheel. So $400 for his mistake.
