Engine Swap??

ive got a 94 cutty supreme 2D with the stock 3.1L 3100 V-6. I was thinking about swapping it out for a better engine for more power. what engine would produce the most power for my car without me having to seriously modify my car? wut else would i have to do to make the engine work, like putting in a new ecm, etc. is there a web site or anything with a step by step video or somethin like that? any help please!

L67 supercharged v6....you'd need to swap wiring harness, transmission, and PCM as well.
