273 to 318 swap in 67 Cuda

Hey guys, help this old guy out.
I have a nice rebuilt, 30 over, 318. It is just a long block. My 67 Cuda has a 273 2 barrel engine. Will all my brackets for power steering and alternator, starter, etc. fit the 1971 318 engine and are the engine mounts the same? Since I'm asking questions, what about the 273's exhaust manifolds, will they bolt onto the 318 as well? I would like to maintain the 2 barrel for now, will the 273 cast iron intake fit or will the ports be smaller and cause problems. I know I need to just get a Weiand or Edelbrock with 4v carb, but not in the budget for now. Any help on mating these 2 engines will be appreciated.
