What is y'alls opinion on these things? I am seriously considering starting a parts pile for a eventual fuel injection/6L80 swap into my new to me Stepside. The mighty yet underpowered 305 runs great. So I will attend to cosmetics, and suspension upgrades first.

One of 2 ways I will do this.

Put the Holley stealth efi carb looking tbi on my 383 LT1 with matching distributor, and hook it to the computer since it can control the 6L80.

Or do a mild 5.3 with a LS6 cam or around that rough specs, better factory intake, and 6L80. Although a Van computer is not out of the question since they could be had with the 4.8/6L80 combo. I would prefer not to do DOD or cylinder deactivation since it can be a bit problematic. Aka no warranty. I will burn the gas instead.
