Build the 261 and buy the adapter that lets you run the 216 valve cover. Replace the rear gears with the readily available 4.57 gears from a 3/4-ton or the 4.11 gears if you can find a set.

That would give you an original looking truck that should easily do 55 unless you do something crazy with the tires.
