Getting ready to swap a 5.7 into my 73 Dart Swinger

What automatic transmission were you going to use? Also, If you want to save a ton of money on a rear end, check out the 8.8 ford conversion. I did this for a fraction of the cost of a 8 3/4.
I was going to use the stock one that came out of the dodge ram with the engine I'll make a final desision when I get there
