How would you build a low 10’s street car

kindof depends on what's ahead of it.
My 3.09 low gear turns 'em into 4.11s off the line, and my 367 takes that to 50/55 no problem. If I short shift, I can split that with my GVod and come out at 65=6900. But now I gotta put it into second.lol

How did you mate up to the gear vendors OD to the commando box? I thought they are not compatible with the ball and trunnion design
