Some basic questions re 727 and 318/360 bolt up

Oh dear, I had thought I read that somewhere and had been working on that assumption. Looking at my plate now it says: 3 SPD NP A-74S.
I like the idea of keeping the transmission and 3 on the tree, but it looks like the easiest approach would be to pull something with a complete engine and transmission - that van 360 will likely be too long for the a100. Back to the scrap yead to look for something else I guess.
