I guess it depends on the owner. I have been tinkering with all things carbureted since the womb. Fuel injection may be able to "do what carbs can better", but EFI can't do it for the same price, or give the same nostalgic feel. Some people are just old skoolers. If the carbs are tuned correctly (with a synchrometer and wideband o2 sensor), there shouldn't be any problems. I had (before it was totaled) a 280zx with a chevy 292 cam running triple webers and it ran beautifully, hot or cold, even thru Montana winter (not too mention plenty of power to spare!!!). And that was with the cold-starts blanked! All it ever needed was a few little idle/mixture adjustments, depending on the weather of course. Once you learn the basics of how to tune carbs, and rejet them, it is sooo simple. Rejetting takes all of 10 minutes. Now 2 of those webers are about to find there way to my 4AGE, due to the fact that it is a redtop with bluetop crap (injectors, fuel rail, wiring harness, ecu) and is not running to is full potential. That and the fact that the cost of the carbs, loads of extra jets, chokes and all other parts required was still cheaper than either buying the redtop fuel injectors, ecu, etc... or buying aftermarket fuel controllers. It is true that the carb conversion is not for the faint of heart!!! You do need some previous experience, but if you know what you're doing, it is well worth it!
I'm not sayin that carbs are better than EFI, only that they are waaaaay more unique, fun, and so utterly and extremely basic and simple. Its all about the DIY! I don't need computers to tell my engine what to do!
Could it get any easier?!?! Lets see this done with EFI hahaha:
