I agree with his recommendation. I would also suggest something better than OEM bands & clutches. It will likely hit hard and quality aftermarket stuff would be more durable.
I ran one in the street in my first car, a 340 Challenger. Under the right conditions, it surprised a lot of people when I was able to chirp the tires on the 1-2 shift, even at low rpm's. But the shifting got to be bothersome after a while. If I hadn't gone to race-only, I probably would have gotten the best shifting valve body that retained the auto feature.
