You can DIY mod carb engine to EFI using plethora of cheap user programmable ECU modules and oem/salvage yard parts, its almost Lego at this point in time with everything understood and tons of documentation in the open. Throttle body, MAF, Lambda sensor, one fuel injector, fuel pressure reg, fuel pump, crankshaft position sensor, ECU, laptop to program and tune the ECU, all in all <$500. As a bonus you get to delete distributor and convert to electronic ignition for free. There are even plug&play kits for early troublesome mechanical fuel injection systems in ~$600-1000 range https://kjetkillers.pl/en_US/c/EFI-Electronic-Fuel-Injection...
You dont need top of the line $1700 Haltech elite 2500 or Link G4X FuryX if you arent seriously racing.
Maybe one day! I also have the option to take the EFI from one of the following model years. I suck at electronics, and the wiring is already a royal mess (wasn't me so!).
