Dummys guide to carburated engines

I've seen & heard horror stories about the after market EFI systems out there. I was toying with going EFI on my bracket car & was looking into it about the same time. I talked to a fellow bracket racer who had EFI on one of his cars & the other still had the carb on it. We talked for a while & he told me that depending upon where all I planned on racing that my best bet was to stay with a carb because of the tuneability. I have built so many Holleys over the past 50 years, that can probably do it in my sleep. Right now, I'm experimenting between a 4779 4 point idle circuit, a 4779 2 point idle circuit, a 750 Street Demon, & a 750 Race Demon. The power valves in them have been blocked & my fuel regulator has a return line on it. I've made 7-8 hits on each carb & so far, the 4779 4 point carb has run the best. I will continue to test them until I find the one that performs the best.
