273 to 340 swap in 64 cuda auto advise needed

Ok, I need help and advise.
Found a 1974 340. What do I need to do to put it in my car. I know the passenger side motor mount is different. Here are some of my starting questions.
1. Is the 74 340 internally balanced.
2. What torque converter is needed
3. What year cast exhaust 340 manifolds will clear my borgeson steering box and steering shaft.
Anything else I should know.
Oh my 65 273 is a 4bbl and it has aftermarket AC.
