Line Lock with Drum Brakes ?

I’ll add to that, HOW is he doing his burnout? slooowly turning tires or like I do, smack the gas pedal hard, 1-4500 2-4500 3-4500 once smokeing good release lock and ease out under power. Let off gas stop back in first move forward under slight power to set spragg. Go to pre-stage line, no dicking around
Agree, though I never start a burnout in first gear with a 727. Manual valve body, start in second, smack it hard, shift into third. Back off throttle before the tires hook.
Edit: Frank Mopar tree'd me.
