hi, so, a V8 conversion eh? that is VERY ambitious! it has been done, but successfully only 2 or 3 times. Putting a V8 into an Eagle is VERY difficult, not like any other car. A better way to go, would be to put in a late model 4.0 stroker. This engine will actually fit into an Eagle, and a good 4.7 stroker will have more power than the average AMC V8 anyway.
Either way you go, good luck, and keep us posted. gz
