Welcome to my Blue Dragon project

Some Background Info
The truck started life as a 4.9L that was EFI, around 2017 the electrical system was giving me trouble and I was getting tired of dealing with junk new part, so I talked my wife into letting me spend some on the parts to convert to a carburetor system, With some help from an old friend / boss I was able to overhaul the engine. Installed a single barrel carburetor and had to make a custom wooden spacer plate to lift the carburetor off the manifold, so the butterfly would actuate correctly. Later I had a steel spacer made to replace the wooden one.

Some of What I am wanting to do

1. Upgrade intake manifold and carburetor to a four barrel.
2. Remove all wiring harnesses and computers.
3. Remove dash and build new custom dash.
4. Fix all rust holes and replace some body panels.
5. Replacing the fuel system.

   Information I Need to Acquire
   1) Since I will be making a new wiring harness, I would like to redo the ignition / spark control brain. ( if that makes sense ) What can I use?
   2) Is there a way to work the A/C system with out using the PCM?
   3) I am thinking about how I would like the new gauges to work; I know that for most of the gauges I would like digital, but for the tachometer and speedometer. I would like to do both analog and digital. So I am think the best thing to do would to make a custom PCB and use something like Raspberry PI to be the brain.? Do you think that would work or is there a better way?
   4) The fuel system is going to have a return line, but I am trying to understand what is better for the fuel filters; stainless steel mesh or paper mesh and what would be the best or better setup for the fuel system, like placments; I.E. pre & post filters, if regulator should be before or after the fuel logger?
   5) If I am using a 12 PSI max pressure. Then should the regulator be rated up or more than 12 PSI?
   6) Would the carburetor I picked out work with the 4.9L engine or would that be to much CFMs?
