1987 Dodge Dakota 5.9 swap with a NV3500

They also used the AX15 behind the 5.2 and later 3.9 plus the 4.7. The NV3500 and AX15 will bolt in place of each other and there's really no advantage to one over the other. They would both live fine behind the 5.2 but I wouldn't expect either one to put up with a lot of abuse behind a stout 360.
