What configuration can be used for street/strip? Is it a 4+1 where 5th is an OD?

The difference between the two are the sliders and face plates on 1st thru 4th gears. For street/strip you would use clutch assisted.
On the G-force 5th gear locks the main shaft straight thru 1 : 1, the countershaft is just along for the ride so no od.
Also Liberty has a similar transmission.
