on the flex plate/torque converter bolts...you'll need to rotate engine (not cranking) to get to the rest of the bolts..

transfer case ...refers to 4 wheel drive vehicles. .it transfers driven power to the front axle

on lifting as a whole unit ...I would be leary of pulling engine and trans with only a carb lift plate..that's a chunk of weight...lift with accessory bolt holes on each head front and back..

sitting a engine and trans on the floor is no problem..engine by itself will not sit upright..youll need to put wood blocks or something under at the front of oil pan to hold it upright

seperating engine and trans on floor is no issue..remove the 6 trans to engine bolts and slide it back..its on dowels so it may stick a little till it clears the dowels
