Rebuild 904 or swap for 727?

I am finally getting around to getting the Dart back on the road. I pulled the 318 and 904 and driveshaft. I have a 1989 360 roller block with 308 heads that will get built for the car. The Ford 9 inch under it now will be rebuilt too. This will be a street muscle car, not a daily and not a drag race car. I have questions:

What internals do you recommend for the 360 (not a stroker)?

Should I rebuild the 904 or swap it for a 727?
If I rebuild the 904, what would you recommend I tell the shop who rebuilds it to use or do?
What converter would you recommend?

Should I replace the smaller 7260 u-joints and re-use the driveshaft or replace it with a larger one and 7290 u-joints?
If replace, what do you recommend?
