As I've gotten older I've come to dread leaning over a hot engine playing with gasoline... forty years ago it was what we all did & never gave it a second thought... These days I think about fire & how even if I get away without getting burned my car that I have so much time & money invested in will get damaged... I've tweaked many Holley's, Carters & even a few Rochesters... None have ever worked as well as EFI, more HP, maybe, better overall drivability day in day out, hot weather, cold weather, sea level, 9,000 feet doesn't matter, twist the key it starts, it idles, it leaves from a dead stop without a bog, a stumble, a flubber....
Many years I made a living wrenching, use to build allot of carbs, I could fix allot of problems, I continued to do carbs long after allot of shops weren't doing them & wondered why other shops were passing on easy work.... Then I got a customer who had a carbonated truck but his daily driver was EFI... I built the OE Holley on his 460, he was thrilled with how much better it ran but there was a problem, only on cold mornings it would die at the third corner leaving his house.... I played with choke tension, choke pull-off high idle steps.... problem was it would go lean just as the high idle fell out.... I made it better but never perfect.. Anyone who grew up driving a carb would expect & accept it... This guy only drove EFI stuff & I couldn't make him happy... Back in the day carbs were fine, our expectations have changed..... And while I grew up with carbs I sure appreciate a good working EFI...
