Digging for info - front drum explosion on 727s

My converter stalls at 5000 hence why I'm around 5500 in 3rd for the majority of the burnout. It's actually a simple process to start in first, shift to second pretty quickly and then to 3rd right away. It's not like you're very deep in the throttle! Then lift and release the line-loc and roll out of the box.
I've yet to do a burnout or stage the car since getting it together as the weather conditions won't allow it....lol

Can't wait for good weather and the tracks to open up next year.
