Crazy idea?

May be the wrong board, if so I apologize, but seem to be a good many mechanical questions asked here.
I have a 1969 Chevy CST10 I have owned since the late 70's and I have restored it twice. Small block (350, 4 barrell, Turbo 350 automatic transmission). I am THINKING about doing it again but going with a fuel injected / electronic ignition V-6 and corresponding transmission. I don't care about what it will do on a 1/4 mile but I would like to basically make it a 2026 model truck with 1969 sheetmetal. I know people do this but most are done by professional mechanics for a pile of money. I can do the work myself, I replaced the other 2 engines and transmissions myself, I am just curious if anyone has ever done it or something similar and what motor / transmission would be a good "fit". I am planning on restoring it this time around from the ground up, off the frame. I know it ain't practical...keeping the thing damn nearly 50 years ain't practical. The truck was my grandfathers (bought it new) and it was my first truck (I had a 1970 Camaro for about 6 weeks before I talked my dad into buying it so I could buy my grandfathers truck). It is a CST truck so it came from the factory with some upgrades for the era...power steering and brakes, factory AC that hasn't worked since the mid 70s LOL. Even has a headliner! At one time it had houndstooth interior (it will again when I am done with it this time). Anyone ever done this to an old car or truck?

I hate to be the guy that says LS swap it,
But if you’re going to modernize the whole power train, just LS swap it.
4.8’s and 5.3’s are all over the place.
4L60 or 4L80 trans should work if you want to keep it auto
BTW: Pics?

Why not just rebuild the 350 and put fuel injection on it?

Terrible idea.
You can probably do Holley Sniper EFI depending on your intake manifold set up but unless you pay big bucks just keep it as it is. That’s the last easy motor/trans to work on without a scanner.
But like previously mentioned LS swap would be the way to go. Will likely require some manifold and exhaust modifications and rear end and axle upgrades. And also all new wiring harness. Talking very time and labor intensive.

My first vehicle was a '68 C10 SWB I regrettingly sold in college 20 years ago. At the time, I had added power brakes, steering and AC. The popular thing at the time was swapping front frame from newer truck. Im wanting to say the front frame was similar from 67-89 with only differences being bolt holes. It was a way to semi-modernize the chassis.
Now, I think the popular but much more involved is doing full chassis swap with newer vehicle of same wheelbase. I think the SWB 115" wheelbase swaps ro a Tahoe/Yukon. I think it swaps from 1999-202x so you can get as new driving of a 1969 as your pockets and ability can do.
There several facebook groups and youtube channels covering this.

This seems like the easiest and best bang for your buck
