First queston is, why in the world would anyone want to get rid of a 3 on the tree set up?? Heck, a 3 on the tree is one of the best antitheft devices around. How many punk kids do you know that have any idea how to operate one? I'd be talking your buddy out of that swap real hard, 360 YES, 727 no thanks. Now if your buddy really wants to do this swap, you'll need to correct year steering collume, K-frame, shift linkage, and motor mounts.
