The box is not installed in the car yet, but with the box mounted in a vise and using a set of vise grips I get a little over 4.5 turns lock to lock.
For comparison, the stock box is in the car, but not attached to a drag link. When I turn the steering wheel lock to lock I get almost 5.75 turns.
With the drag link hooked up and the rest of the steering I think the number of turns lock to lock will be lower. I seem to remember closer to 5 turns lock to lock with the steering all hooked up with the stock box. The Flaming River box should be closer to a power steering box which IIRC is around 3.5 turns lock to lock. I will report back when I have the new box completely installed.
