    I can pick up a th400 for free, the problem is that it is out of a Heep Wagoneer with a quadratrac. This is where my question comes in, I figure I would need an adapter plate to bolt the engine to the tranny, (or at least drill new holes in the bellhousing) what would be involved with adapting the back of the tranny to the NP203 in my rig???
    Thanks

    Ring up the boys at advance adaptors. They have everything for this kind of stuff.

    The AMC version of the TH400 has an AMC bellhousing bolt pattern, and will not work with a GM engine. You must change the tranny case. All the internals, except for the output shaft, are the same.

    Thanks, it doesn't sound like it's worth it.
