I have a mechanic friend (a real mechanic, not just a 'parts-installer') thats a Holley guru that would agree with you 100%. I'm still not sold, but i'll concede that if everything is running/tuned perfect, the carb could at least be damn close. There are some pretty damn smart builders/tuners that still dont like EFI... even for MPG.



True. You can get a carb to be within a percent or two of an EFI, and at WOT they do tend to make mroe power than acomparable street injection. However, the big advantage of the efi is its learn on the fly adaptability over a wider range of conditions.

With that said though, I've never wanted to put one on my truck beause the payback over the carb I have tweaked within an inch of its life, is so long it would never really pay for its self in fuel savings.

BTW, the new Street Demon carbs are a bit of a hybrid AFB, Thermoquad design. You can get them with a polymer body, they use AFB rods and jets, they have small primaries with a 3 bbl design for the secondaries. Of course they will cost you some dough over swap meet stuff.
