It is possible to artificially increase displacement by supercharging. To get a 327 to ingest as much air as a 427 would take about 5 pounds of boost which is quite doable.

Or you could get practically the same HP boost with conventional means such as cam, carburetors, header, valve work etc.

I think the supercharger would be better and cheaper. As long as you don't go too high with the boost no mods to the engine would be necessary. For certain technical reasons, your engine should respond well to a supercharger.
