Industrial slant six?

The short answer is YES. You will need to keep the bolt ons from your Cuda.
Like the oil pan timing cover etc. the tractor will probally use a govenor set up. All slants I have seen were drill and tapped for the accys. Ceej is correct about the years and crank pocket. Remember your tranny is a 1 year only if its a 904 Auto, but it will bolt up to any slant engine.
The Tractor may have the shot peened crank 8).
Have fun and ask questions along the way,
