its all stock LT1 drivetrain... lol, tires are smooth as glass at 80 in 6th... i was just wandering if the tranny has a little wear, the rear output bushing seems like it has a good amount of play in it? the motor mounts are good, the tranny mount needs replacing... (that is prolly the majority of it) i just wandered if you guys had the same sort of problem... prolly no big deal.
