63 Dart 225 /6, pushbutton 904, drive shaft or V8 conversion stuffs

Hey FABO.
I have a 63 Dart GT convertible without a drivetrain. So, ideally, I'm looking for...
225 slant six/pushbutton 904 combo and
Drive shaft to drop in and make it go.
Or...
Everything to make a 80s 318/727 work.
Motor mounts, 64-66 V8 K member, dropped center link, and floor shifter.
Let me know what you have and what you're asking.
Thanks everyone.
