EFI vs Carb
Wondering what your thoughts are on the two. I currently have EFI on my 1988 302 but am thinking about switching over to a carb. Anyone have any input on this as far as pros and cons or preferences go?

There is a reason why every auto manufacturer in the world has switched to EFI. It works, its reliable and its simply better. I have a 74 pinto stationwagon as sort of a toy, and I switched to EFI from carb and dont regret it one little bit. That old carburetor and points ignition system was just too unreliable and problematic not to mention severely outdated. The only carburetors I run now are on my small engines - and if i could get them injected , or diesel for a reasonable cost, I would. So I am doing the next best thing which is converting to a carbureted PROPANE setup on those. (But thats another story)
It isnt worth it by any means whatsoever to convert to a carburetor from EFI. Nor is it easy. The same can not be said for the opposite tho. My EFI conversion in the pinto took six wiring connections to make it run.
If you do anything, do what I would like to do on my F150 - put in a 4bt cummins, or switch to a NEWER fuel injected engine. Havent decided which I am doing yet. But I have the parts to convert to mass air fuel injection and most of the work is already done. Beats the heck out of the speed density system found in your truck and in my truck from the factory.

It's a Canadian thing eh!
Carb and EFI have their pros and cons. A new carb bought today is much more advanced then what you got 30 years ago and is much simpler to tune and install but its performance is only as good as its fuel and air mixing ratio and unless you have a separate system to monitor it, its up to you to achieve its best performance.
EFI does all that for you with O2 and other sensor sensors that actively adjust fuel/air ratios on the fly by being able to monitor each cylinder or bank. Main reason was keeping lower emissions but being able to achieve the best performance possible. On top of that it helps immensely with diagnosis that would make repairs on modern vehicles almost impossible to do or very difficult without knowing what you are looking for.

How did I know that TBS was gonna be part of this? I had a 4.9 that was carb and I loved it and this is the first EFI truck I have had. I know that the cons outweigh the pros by a long shot on this but I guess I'm just looking for that answer that hits me and says are you kidding me.
