Gonna be a long thread, I'll bet. 100 readers, 100 opinions. I owned and ran a fuel injection shop for a few years, and so I've got mine. A properly designed and properly set up closed loop EFI should give the best of everything: economy, performance, driveability. An open loop EFI gives a pretty good chance for the best of everything if you accurately estimate and upload the response settings. A carburetor in my opinion works on the same principal as the "there's no substitute for cubic inches" argument. It uses brute force by pouring in a lot of fuel pretty much all the time. The excess burns off in the exhaust system. On this basis LotsOfFuel + LotsOfAirIn + BigWellTunedExhaustOut = GoLikeH*ll. It usually also means not-so-great mileage and lots of emissions issues. BUT carburetors and manifolds are usually a whole lot cheaper to build than the EFI system, particularly a closed loop setup, so carburetors are still hanging around where cost is a big issue and the EPA is not.
