Hmm...
440-4V
727 tranny
3000 rpm stall converter
2.76 rear end
To my untrained eyes it seems like there is a lot of cam in there given the 3000 converter. A little shy on low speed torque? Then the 2.76 rear to start moving the car? Or, has this guy been revving the car up to 3000 rpm before he takes off? While the exterior is a disaster in itself I would be concerned about what he did to the engine.
