4.3 TBI to 4.3 carb swap
I don't have power windows, and can't I run a new standalone speedo? Along with whatever other gauges I want to run? You say "A lot of the convenience features you rely on every day", but interior lights is the only thing I can think of besides the radio...
I'm told that an inline pressure regulator will handle this.
The goal here is to step away from the complexity of the TBI system. Mine has given me nightmares and I'm not very interested in keeping the system.
I feel that maybe I should mention: I'm currently pursuing my B.S. in Electronics Engineering so the idea of running a few wires or creating a couple circuits with toggle switches is not intimidating at all.
Basically, my ultimate concern is can I stick this new motor in, get the right fuel pressure, feed vacuum and power to the required components and drive away? This is based on the fact that I have no electronic components in the cab beyond the interior lights and the radio. If I can buy a 1945 chassis and do the same thing, why can't I do the same here? Sure, I'll lose some modern features but I'm fine with that.
These are honest questions, to be completely up front I just need a reliable, easy to work on set up right now. As long as I can monitor the things that will leave me dead in the water (temp, oil pressure...), I will be a few orders of magnitude beyond the sputtering, high idling, gas guzzling crap I'm dealing with now...and the only solution is to throw money at it and hope to "hit the jackpot"...with a carb sure I won't get the greatest fuel economy, but if something goes wrong I think it will be immeasurably easier to hunt down the issue...no?
