For a derby car, you want reliability.

I'd keep it to the stock spec's AFA clutches/steels but use a good quality set. Looser clearances aren't wanted or needed, IMO. No extra holes, other than ones to help drain fluid from the clutch basket, if they're not there already..

A 34 element sprag and a tight converter (less heat) and you might consider boosting line pressure and/or shift kit might help transition quicker from reverse to low. Someone else might be able to say what would be needed to help with this.

I'd use a good, racing-type fluid if it were me. B&M and others sell high performance fluid that resists heat better than normal fluid.

I don't know what will happen if you were to use the hydraulic fluid on a daily driver, or switched from it to ATF. If the tranny is only gonna be used in a derby car, prob. moot point.
