I see you red-lighting as the car rolls forward out of the pre-stage light as you rev it to 5K, then when you dump the clutch a Ujoint, the clutch disc, or the rear let's go... lol. My 340 did all of those, on full radials (no drag radials back then), on the street. You have to find the weak links before you really can get consistent with a stick car.
