So I decided to build a 360 for my Valiant :)

For me it doesn't interchange with my set up I have a 340 so to have a 360 as a spare Id need the trans and flex plate/flywheel etc. Isn't really anything about the 360 engine itself, more about interchangeability.

I am curious, why would you need a different trans to go from a 340 to a 360?
