Hey everyone, I was thinking about swapping my old 216 for a 454 BBC and turbo 400 trans in my 48 3/4 ton. What will I have to do to my rear end to make this work; do I need a new drive shaft? Will the stock gears in the rear end work okay?
Also is there anyone out there that makes engine-trans mounts for this set up? Will I have trouble with my steering clearance?
What’s everyone’s general opinion on this swap? Would you do it? Is it hard to do?

This truck is a work truck for a woodworking/cabinet business, but I don’t actually use it that often so gas consumption is not a huge issue. I also want to be pinned to the seat every now and again when I step on it.
