Well to answer the drive shaft question first for reason 1 for reminding me that i still haven't made a new 1 and 2nd have 3 passes on stock factory shaft in a 3600 lb car that went 10.70 on a lazy pass behind a 500" indy motor making 740 to 780 hp w/no problem (1st and 2nd pass left it up to someone else to air down the tires so) 2nd nitrous is the easiest bolt on per $ for increased hp and torque
