Quote: I think it is a production motor that came out of a car that was never stamped. All warranty and service motors I have ever seen (around 8-10) have a W, S or WT on them. Does the paint look correct? Warranty motors were not painted. Again - I am just thinking out loud here - without the key piece of history it is next to impossible to nail down. It is easy to speculate though!
Take a little closer look to the left on the bellhousing area and you'll see part of a metal tag that is "nail riveted" there. Also I think you can just see painted on large letters for I think the piston to cylinder fitment tollerence on the side of the block, were those on warranty blocks?
Purchased for an Excalibur Kit Car from a Chrysler/Plymouth dealer in 1969 is what I was told so I guess I have to talk to the person who bought it..pretty good story none the less
