Depends on who you are I guess.
I couldn't rebuild or tune a carb if I had to, but I was able to swap a fuel injected '92 5.0 HO into my '97 Ranger with ZERO problems using factory Ford wiring harnesses that I spliced together. Everything worked perfectly the first time... all the gauges and factory tach, check engine light, reverse lights, ignition, only starts in park or neutral, cooling fans... crazy, huh? No AutoZone triple gauge hanging under my dash, no monster tach on the pillar, the engine started perfectly on the coldest days of winter... the fuel injection was so dependable that all I had to do was drive it!
