    As far as space yes it will fit. You did mention the motor mounts. There shouldn't be much of a difference in the mounting of the 350 with what you have in there now. GM is pretty good at keeping their mounting points in the same place rather it is a buick, Olds, Pontiac, or Chevy. I would however not go with the headers. You may find it a bit too restrictive. (When working on the engine) you may also need to add and overload spring or get some spings from a car that already carry a 350. There is about a 150 to 300 LB difference in the two motors. But it can be done.
