Advice on what to build from the parts I have on hand

[51Chevyman]

To all, I have a lot of parts and want to build a truck to run on the dunes and to pull with. I have a friend that has a short box 96 Chevy with a bad motor that he will sell me and I want to use that body. I also have a 78 blazer that the body is shot with a 350, 350 turbo, Dana 44 front end, and a 12 bolt rear, 203 transfer case, and a 4 inch lift. I also have a 68 Cadillac 472 with a turbo 400 long tail shaft. Is there a way I can bolt a transfer case on to that transmission? The last thing I have is a three-quarter ton long box 73 to 87 Chevy frame with a 14 bolt rear end 2 wheel drive. I would like to use the 14 bolt rear end and probably the Dana 44 front. I would like to know what your opinions R so I can build A heavy duty holler and four wheel drive for the sand dunes here in Michigan. So come up with some combinations that you think would be good from the parts that I have thank you.
