Dragging this oldie back up since I was looking for something else, but Just fyi, a cu730 IS a bolt in, IF you buy the correct rubbers and top brackets.
isolators: GM p/n 06264100
top brackets (for the individual style brackets as on the 1983 models) GM p/n 14039949 and 14039950 (left and a right).
You can modify your stock radiator shroud, or find one in a wrecking yard out of a truck with the tall 3 row rad that'll need minimal modifications. Good luck finding an original app shroud for the cu730 though.

Original radiator applications are all over the map, one year it'll be with heavy duty cooling, other years the 3 row will be spec'd for heavy duty cooling. Ditto for a/c applications, sometimes yes, sometimes no. Been used with everything from the 305+ to the diesels, and even though it has an transmission cooler, its also used in manual transmission applications.
