I'll get the swap thread going.

Basically this - 1987 with a TH400 and 4.10 gears and 454. 9mpg if I kept it down at 60mph.

Pulled a NV4500 out of a later truck, sourced clutch/brake pedal box out of a late 80's square body, cut a big hole in the floor and stuffed it in.

Makes for a WAY better driving experience. First 2 tanks were over 11.5mpg and that was with a 6K trailer and a lot of 65-70mph freeway.
