I got the 318 short block already put together. It was seriously built buy a racer I know very well and I got it dirt cheap and was intended to go into my Warlock. If I would have to start from scratch I would probably do like you described but I have been very busy and want the car running for Mopars At The Strip, Sweden August 1st and next week i will be away for work so I need it finished this weekend.
Here in Sweden you can't 'just pick up a cheap 360' so you have to work on what you can find.
Pistons are KB167. Will ask my friend about the rods and the other, I forgot what he told me.
See my answer above for what I actually want to do.
You might be sitting on the long runner tunnel ram I'm looking for? ;)
