This thread should be closed. Anyone else down the road looking for similar advice will gain nothing from any of this, except for the fact that's it's easiest and cheapest to buy the model you really want, and doing swaps in modern vehicles is a nightmare unless you have all the parts and unlimited funds.
This ain't like it used to be, when we'd swap a 360 in place of a 318.
I don't care one way or the other whether or not the thread stays open, or gets closed, but everything else hits the nail right on the head.
Swaps ended for me around the 2000 model year. I was able to take a 2000 GMC Jimmy 4.3 V6, throw all the failure prone electronics in the trash, update the gaskets to better Fel-Pro stuff, and install an Edelbrock intake, carburetor, and a HEI ignition, then put the engine in a '89 S10 Blazer. That engine suddenly went from constantly breaking down, failing emissions (in a '00), and constantly misfiring, to being the most reliable and FUN vehicle in my fleet! Only lost 0.5 MPG, but gained exponential throttle response, starting speed (like 10° of crank rotation and VROOM!), significant gains in the low and midrange, and a TON of top-end power. I'd have kept it if it didn't rust away to nothing. Wife drove it most of the time for winter commuting in MA - the road-salt capitol of the world.
Nobody could pay me enough to tinker with today's electronically controlled, networked, and over-moduled rolling Tupperware of the later '00's. The quagmire of electronics-related driveability issues would take ALL the fun right out of it. Eff that ... with a BAT!!
Today, if you want to tinker and enjoy some of it, buy something built prior to the 2007 model year. If you want to tinker and not get pissed off, swear, or throw tools at all, get something built prior to 1995. If you want simplicity in everything, buy pre-1973.
Even as late as the early 1990's you could still take apart a power window switch, clean it up, lubricate it, adjust the tension to your liking, and have it working better than new after 3-4 decades of constant use. Every electrical problem I've had in my Cummins-powered '93 Ram W250 LE was fixed by doing just this. No parts needed!
With enough money you can make ANYTHING as fast as you want, and handle & stop as great as you want.
