The easiest thing to do is swap the 360 into the older van, the frame is different, oil pan, transmission, computer, wiring, motor mounts... about the only thing that is the same is some external sheet metal. The 360 will bolt up to all the 318 stuff including oil pan.

I have 2 of the 94 style, 1 of the 01 style and one of the 92 style.
