Which one is better? (long)

I could use a 727, as i have several. I am using a lockup 904 because this will be just a cruiser. I already have a race car. I plan on using as much of the 96 wiring and stuff as possible. Car will also have a stock width dana 60 in it. I have a wiring harness relay box from a guy on FB that removes unnecessary wiring and makes the harness plug and play. This will be our 4th car that we are building. We have a 37 Chrysler, a 49 Plymouth, a 52 Dodge and now my 71 Dart. As far as buying things, i have most of stuff now. Was not planning on buying a gas tank but cleaning it did not help it. I will probably send the PCM out to be programmed or get a stick shift PCM. It will also be OBD 2. I will be putting O2 sensors in it and what ever it takes to make it a good driver. Thanks for all the replies so far. They have given me a few more ideas and things to ponder.
