    88 and later 700's are supposed to be better than earlier 700's, but if you are going to build it then it doesn't matter because you will just have all the updates done when it is being rebuilt.

    They're all equally worthless. Do a search. /forums/images/graemlins/smile.gif

    The difference is (IIRC) '87 or '88, when they went to a diffeerent casting, which has an auxiallary valve body.

    You can tell this change (and thus general vintage) by a large half circle cast into the passenger side of the tranny case, that passes through the cooling fitting ports.
