I have daily driven my C10 with the ProFlo4 on 350 for 6 years which equals about 60k miles. It hasn't left me stranded. It has some glitchy issues. Mostly the TPS likes to jump around on me randomly which just makes it idle a little poorly. I've never been able to dial in the idle so that when cold it doesn't die when I put it into gear. I have to rerun the wizard every few months because the part throttle acceleration starts getting rough. If I rerun the wizard, it runs great for awhile. It's almost like the fuel table gets corrupted. Even slowing down the learn doesn't help. Every once in awhile I'll be driving along and it just cuts off for a second but then keeps going. Every time I wonder if it's gonna die for good.
I also have the Edelbrock trans controller running a 4l80e.
I wish the Edelbrock software allowed more customizing like the Holley Terminator. I like the Terminator running the factory efi on the GenVI 454 in the crew cab much better in that regard. I think of the Edelbrock ProFlo4 being like an Apple phone and the Holley Terminator is like a Samsung phone. Edelbrock locks you down like Apple and Holley gives you the freedom to mess things up.

I thought I read that Holley ECU can't run the factory GM injectors?
I put LS1 injectors in the factory fuel rail. I don't know if it could have fired the OE injectors, I needed higher flowing injectors anyway. Running the Terminator also let me run coil near plug.
Since you haven’t gone down the LS rabbit hole yet, I’ll dispel a couple of things you are worried about.
Engine/trans mounts and driveshafts- get the right swap mounts for the LS and the engine stays in the same spot as your sbc as far as the bellhousing flange goes. Meaning trans crossmember don’t move, shifter for the t case won’t move and the driveshafts you already have still work.
Aside from that how much more you have to get really depends on what you have to start with from a donor vehicle. I’m talking about accessories, serp drive, intake and exhaust manifolds, harness and controller.
Saying an LS swap is cheap is completely dictated by that start point. In my case I got a 5.3 for free but it was a long block. Had to scrounge every nut and bolt and part to attach to it for it to work. It was not what I considered cheap even with discounts on parts when I was at the dealer.
In some cases it’s cheaper than a pro Flo, some cases more.
