Looks like it has a Pinto engine.

“1951 Willys M38. Has a Ford engine in it but the rest of the drivetrain is original. Was going to restore this one but don’t have the time. Does not have a title as the PO got it at an auction and recieved a CJ2A title. Paint is partially removed from the body with only small amount of surface rust. Sat in a shed for years. If this ad is up, it’s still available. Asking $2,000.”
