Came across a Holley carb for sale. The list number is L-8006. All a search revealed was 2 carbs on eBay showing 75-76 Plymouth, 318-440. It has an electric choke, and a bowl vent, in addition to some extra vacuum ports on the baseplate. Is this an emissions legal replacement for a TQ? I know its a 600cfm vacuum secondary carbs, but has anyone heard of that list number? I want to get something to replace the 1406 on my Fury, and as much as I want to run a Thermoquad, I don't want to run an adapter plate (dual plane M1).
