I am a proponent of EFI on street vehicles but, I am also a realist.
The fuel injection properties are well known however, F.I. proponents seem to always point to a POORLY tuned carburetor and then profess to tell everyone that the F.I. system NEEDS to be tuned correctly - we should compare "apples to apples".
ALSO, those same proponents seem to conveniently forget, (or they were ignorant of the facts), that there are numerous carburetors in the marketplace which change themselves to various conditions with internal altitude compensation and O2 feedback to constantly readjust the air fuel ratio to a constant ratio.
Although the "time" was short lived because of the oncoming popularity of EFI, there are MANY "production" quadrajet carburetors which do this, (along with lots and lots of 2 barrels and 1 barrels), and Holley DID sell high performance versions of those very carburetors; I personally have a 750 double pumper with those properties. They never had the chance to become popular BECAUSE of the oncoming of EFI however, they ARE out there.
