On my L98, I used a Carter Crossfire Injection fuel pump that puts out 12 psi. A regular regulator will knock that down to wherever you want it. The fuel pump was a measly $30 off fleaBay brand new.
I had similar reasons to convert to carb on my car as the OP did: Crappy condition of the wiring mainly.

That sounded really smooth to me.
I've owned only one car with a carb...1981 Oldsmobile Cutlass LS 4-door. That car was so smooth, at times you could not tell whether it was running or shut off.
I don't think anyone can deny the advantages of fuel injection, which is superior in almost every way. The simplicity of a carb though...it can't be beat.

I think as to simplicity it depends on your experience. I tried carb swapping my 84 years ago. I couldn't make it run. It would start and die. I never figured it out. I was beyond frustrated. I'm a computer nerd so for me it's so easy to just plug a laptop into the car and it tells me what's wrong. That same car is LS swapped now with a Holley ECU. I can tell my exact AFR and set spark advance however I want. I don't have a clue how to tune a carb or a mechanical distributor. So for me fuel injection is much simpler. I also can't data log a carb. To be honest I have no idea how guys did it for so long before fuel injection. Hell I can't even see how rich my engine is running by looking at spark plugs being I run E85.

I think it's safe to say that even the most advanced tuners would have a hell of a time diagnosing that.
Performance-wise, the biggest drawback I've seen on carbs (from Westech videos) is fuel distribution, where one cylinder may be fat and another lean. This is mostly due to manifold design, air speed and fuel coming out of suspension. Then again, I've seen posts where the TPIS minirams have something similar on the 2 front cylinders.

You are definitely correct, some cant tune a carb on a lawnmower but are a Wizz on fuel injection and vise versa. Ive been blessed to have experience on both for the last 25 years. Both fuel injection and carbs have there spot. However i may be doing the holley sniper 2 in the near future lol
I'm so sick of dealing with carburators I'm trying to remove them from my life. I already have a nice electric chainsaw, weed eater, and poll saw. Next is to trade in the four wheeler on something fuel injected and then a simple fuel injection kit for the mower. My hatred of carbs runs deep.

It's funny you should say that about the lawnmower. This summer I might be fuel injecting my zero turn. 🤣
