I think a built 383 is the way to go, something built for torque. If you could get 350 hp with 500 lbs/tq you'd be set. Though a turbo would be cool I think you will run in to far too many issues making it fit. On my TD the turbo is mounted at the rear of the engine in the center of the block, this is because there is no room to fit it in the front. Maybe someone could do it, or a pro-charger??? Either way, I think a built of NA engine could give you enough balls.
