Quote: A follow up question. If I drag race with a stock VB and shift kit, do I risk over-spinning the trans in the water box in first gear?
No, Not with the low band also holding in first gear.
The "problem" is when you have a VB without a LBA in first gear. The sprag is then the only thing holding in first gear. If that lets go, then the drum will spin roughly twice engine RPM and the stock drum just can't handle that and can come apart.
