Depends on the year and bodystyle

No

Chevy 350 is just what we call that motor because Chevy is the most popular of the gm lines, but really its a GM 350. Having said that, a Buick, Pontiac, Chevy, or Oldsmobile motor are the same motor for the most part. There are som exceptions with the Cadillac motors but that's an other story. should be smoothe sailing for you.
In 67 Buick didn't have a 350. It would have been a 340 or a 300 possibly a 400.
It might. You'd need to check the diamter of the output shaft of the trans.

yes if the engine and trans. are both Chevy or Buick or Oldsmobile Buick/Oldsmobile and Pontiac will inter change but Chevy has to go with Chevy
yes and no yes in that it can be made to fit no in that a Chevy transmission has a different bolt pattern than Oldsmobile's, Buick's, and Pontiac's. the motor mounts are also probably going to be different. However you can change the motor mounts and there are companies that make adapters to use a Chevy transmission with a Oldsmobile, Buick, or Pontiac engine. I have seen an adapter to use a ford transmission with a Chevy engine.
