1953 GMC 270 straight 6. 75,000 original miles. I took a picture of the odometer. This engine came out of a eastern Washington fire truck. It was maintained very well. I have a couple of short videos of it running just after I pulled from the truck. It does not blow smoke. The oil looks good. There a genuine "GMC" stamps all over this thing. Even one of the bolts for the carb has a "GMC" tag still installed! Very rare I this complete/ original condition. I can send more pics. $800 obo call or text 206.571.6165
