One thing you can bet on is that it has been done and with the electronic kits the E series are not the problem they were a few years ago. We put a GM TBI on my 270 as a demo several years ago. Mostly a junk yard setup. Now there are several kits that would work on the 302.
I have a civilian 302 with a Hydra-Matic. The engine is frozen and I can not get them apart. I really haven't tried too hard. I do know that the blocks were factory mated to the housing that the trans mounted to. I don't know how that compares to the later automatics. The torque converter is a totally different animal. Two piece withs a big cork gasket and a million bolts. Some GMC cranks had 4 bolts and some had 6. Hot riders sometimes drilled the 4 bolt cranks to 8. You will probably have to build or modify a modern flex plate to hook up a modern torque converter. The old hydros built right are bullet proof but you will want an OD of some sort for today's driving. Gear Vender?
