Having 2-3 shift overlap - Thinking of switching from 4.2 apply lever to 3.8 - Any Other Thoughts?

Does that rmvb have low band apply? What are the clearances in both drums? How many clutches in each drum?
No low band apply. It's been a long time since it was built so my memory is vague. I don't know the clearance #s but I believe it has 5 red clutches. These days, I take much more detailed photos and notes of everything I do to the car. I should have done better on tranny build day.
Haven't had a chance to take it to the track yet but if that happens, I'll do my burnout in 2nd gear.
