Just want to get a general feeling of how everyone feels about engine swaps in the CUCV line of trucks. My engine is fine as of now, I just want to poll the crowd here and see everyone's opinions.

I have a blazer now and I always tell myself that if/when the 6.2 goes, I would love to have a 383 gasser with a 4 speed. I have no emotional connection to the diesel. I would probably get a GM Performance HT383 crate motor and use my TH400 with a new torque converter until I found a 700R4. Some people prefer building engines versus buying crate engines and some people would replace with a used 6.2 or a new 6.5L crate motor.

What is your opinion on CUCV engine swaps and what would you do if you were swapping engines?

The 327, 350 are good alternative crate engines too and yes, I like the alternative to OEM. Would seem more efficient to do tranny at the same time as engine. What gears do you have? With higher rpm for today's engine, rpm may be an issue. Did you search for prior discussion ?

You should consider swapping a Cummins 5.9 12v into it. Easy swap and its an all mechanical motor, that's arguably the most reliable motor ever made. Also you can turn them up and make good power with a screw driver and Allen wrench. If you want more power then you could throw a set of injectors in (30 min job) and a new turbo. Also it would get better MPGs then the 6.5.
Just my 2 cents.

I loved my 12v in my Ram when I had it. Downside from what I have read, it is hard to put a 12v into a stock squarebody 4x4 without a lift. And 12v are heavy! They weigh almost as much as the 6.2/trans/transfer case combined.

Dending on what your version of heavy is, they might be. They around about 1100 lbs, as for the height I can't speak. I don't have any experience with CUCV's.
However if I had to take a complete shot in the dark, I would imagine a set of new Heavy duty springs would over come the weight and height obstacle.
Again just taking a shot in the dark as I have no experience with the CUCV personally.

In this situation I’m not looking to go down the diesel route outside of a used 6.2 or 6.5.

Ease of replacement is high in the priority list

At my age 60+ I'm looking to make things easier and less challenging so with that in mind I'd stick with a 6.2.
Twenty years ago the answer would be what ever engine I have or afford will fit one way or another!
