Anybody ever put a small block in a Jeep body?

i have a 408 that needs a home and while shopping around I found a Jeep DJ body (postal Jeep) with the sliding doors on the sides. It's 2 wheel drive and I know they originally had a 727 in them so I would need to build motor mounts and exhaust. Weighs 3400 and has an 80 inch wheelbase, can we say squirrelly?
