You would have better luck finding the Engine and tranny seperatly. FYI, AMCs used torqueflight trannies in 1975-78 cars behind the 360s, 401s and some 6 cylinders. The 440 makes the most power in 68-71 with the 4 barrel carb. These motors are rated at 375@4600HP and 480@3200 torque. As for the 6 pack, this motor is rated at 390@4700 and 490@3200. But the 6 packs are rather coveted. You will have a lot better luck finding a good 4 barrel.
