UPDATE: Price dropped to $3000.
(03/25/2020) It’s powered by what I believe is a MerCruiser boat motor (maybe this one?). Custom top? I don’t recognize it.

Yes Dave…….that appears to be a MerCrusiser 4cyl. engine that was based on the GM Chevrolet Chev II Nova engine from 1962-1970. GM sold the 153 cu. in at first and then there was a 181 cu. in version later. They were a great little motor with a few HP upgrades from the Chev II. I have several of them. One may work it’s way into a Willys and the other was a spare for the race engine in my old dirt track midget race car.
