    My mechanic has been taking care (last 25 yrs), of a 1942 MB Korean survivor. The owner was out driving the jeep when he thrown a rod. Does anyone know where to find a rebuilt motor for his jeep. Everything's stock including the 6 volt wiring. If not a rebuilt motor, does anyone know who would have a used motor in good condition. They are looking for a motor if possible that is a drop in without having to rewire to 12v and keep the same era if possible. Any info is appreciated. Thanks.

    Try a "want" classified on this forum.

    Also there are specific military Jeep sites elsewhere on-line. The MVPA club also could help.

    I doubt an F-head would "drop in" to an MB - that's why the M38A1 was developed with a higher hood.

    It would be helpful to put your location in your post or in your signature file.

    Pete's right - The F-head engine is too tall for an MB without either cutting a hole in the hood, or changing to a very short carburetor (and different air cleaner?) ... there is a Holley from a Ford Falcon that's supposed to work, but I don't know the details.

    The primary military site is the G503 forum - http://g503.com/forums/

    Walcks Willys Jeep Parts, Restoration & Wiring - Walck's 4 Wheel Drive Willys CJ2a, CJ5, Willys Truck, Wagon & Jeepster parts sells new reproduction engine blocks. Depending on how bad the existing engine is, any competent machine shop should be able to rebuild that engine to like-new condition. Have you checked with local machine shops about rebuilding your core? You could also call Walcks and ask if they can recommend a source for a replacement engine. Building these engines is not difficult or complicated, if you can find a usable block, head, crank and rods to start from.
