383 into 70 Dart Swinger

Mounts, exhaust, and a transmission, and kickdown linkage if needed. If you use the 400 style water pump housing, the radiator should work too if it's in good shape. I've used the factopry 318 bars in a 383 before. In fact, the LA V8 is only about 100lbs lighter than the B wedge when dressed the same.
