This engine came from an estate and was supposedly rebuilt or very low hour before being stored inside 30 years ago. Can not verify as the has owner passed away. Engine appears complete and very clean. We did not find any cracks or welds in the block or heads.Under valve cover looks like a low hour engine, no sludge or rust. It is set up for propane and has hardened valve seats and propane intake adapter. The only problem we found is a mouse built a nest in one of the exhaust manifolds and may have hung one of the valves open. Engine will turn over and stop in the same spot.
We got as far as pulling plugs and one valve cover but never went further. Please feel free to ask questions. The item "1963 GMC V12 702 Engine Twin 6" is in sale since Sunday, July 18, 2021.
