how did you get the Colored (Purple) text ?When Autolite was purchased by Allied Signal there carburetors had long before left to become Motorcraft units. The Summit carb is, for all intents and purposes, a repop of the Holley 4010. As far as to the lack of success of the 4010, here is a snippet of its history by a former Holley employee:
The 4010 was released in 1986 as a response to the perceived threat from the re-released Carter AFB. The idea was that we'd have a polished aluminum finish and no gaskets below the fuel level - just like the Carter. The carbs were always intended as street use only - not for competition, and only a couple of boat engine manufacturers tried them - notably Volvo Penta.
They were not bad carbs, but there was never a real reason to buy one either. They were limited in power output (small metering passages), still had the power valves that everybody hated (for all the wrong reasons), and actually cost more to make and thus sell.
