1965 Valiant 200 convertible (minor project)

Looks like an '80 model engine. Makes me wonder what they did with the original transmission and converter to match the later crank.

What is different about them? I've also seen some mention of the throttle kick down cable and other comments about mating the engine/trans. I'm a bit clueless about that stuff. How can I tell if it's bit done correctly?
