    Unless somebody swapped in a GM 2.5 you have the AMC. AMC made jeeps until 86 then chrysler started and they were the ones who put the GM 2.5 in. Just think, what if they had put in the 350 instead?

    The dealer or others with the right book can usually tell you from the long serial #. Or, sometimes the smog decals under the hood are specific. Or, show it to a jeep mechanic. Good luck.
