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.
No not even close. Chevy redesigned them in late 1999.
if it is the same motor yes, but some may have different mounts or wiring plugs
small block and big block motor mounts are the same, so you should be able to take V8 motor mounts from most any Chevy engine bay.
318, 340, 360 all take the same motor mounts.
