[66birdman]

I have a 66 C15 with a 351E and a SM420 in it and I was just given a freshly rebuilt 250I6 out of a 74 Nova. Any ideas on what would be required to swap it in there? Motor mounts, cross member and a bellhousing I assume. Anything else I am not thinking of? I really dont want to ditch the 351 but parts are hard to come by and stupid expensive.
