SuperDuty running gear under highboy?will it work?
 

:-huh would it be hard to swap a highboy body onto a superduty frame?

Depends on what you call "hard". I once put a 427 in a Datsun PU for a customer. In high school I put a 327 in a VW! I've got a 472 ci Caddy engine in my 68 hauler..............Define "hard"......................:confused::)

has anyone ever done this?

I looked at a late 80's or early 90's short box truck about a week age that has the super duty running gear under it. It is in Prineville.
