How do you do a burnout in an automatic?
another thing I use is the limiter in the msd 6al....i connect a 3 step to msd box..
one of the steps controlls the rpm while the line lock is engaged....had to replace seveal pushrods in my daughter's Dart before i got it installed.
2nd step controls rpm while engine is on transbrake...
3rd step limited rpm on engine going down the track in case of part breakage...or someone shifting from 1st into neutral...lol
