    Default " Danny and Kim, I was thin

    " Danny and Kim,

    I was thinking the same thing as Kim... but apparently there was a Detroit Diesel 4-51, also a 2-51. The 4-51 is 216cid, and was built around 1950 - ?. I have a Service and Parts manual. I will send you an email directly Danny.

    Regards,
    Andrew "
