If the allison is a MT545 or 542, you will have no over drive or lock up and this will make for no good mileage in a pick up without a really high gear such as a 3:07, or higher. But, you can put a different transmission behind it. The factory front suspension can take the weight. You can get different front springs, and you can get heavy duty suspension components for peace of mind, or swap a 73 up suspension under it and get the pieces you need. (i'm not certain the 66 is the same as the 68 up stuff) A 4bt would fit better of course. But if you got a deal on the 6bt and that is what you want, you can make it work.
