the early Carter Competition Thermoquad, was obviously a high end copy of a Qjet from day one, it had the single venturi booster like a 455HO carb, bigger primary bores, dual floats, dual needle valves, phenolic center. One look at the top, you can tell they copied a Qjet, and improved the fuel delivery. A single inlet line splits into 2 feeds internally. Not to be confused with the production Mopar Thermoquads, these used unique jets, and some other one off parts.
Back in 2000-2010 they were on Ebay for $75-$125 each. I sold all my Qjets but kept these. Picked up half a dozen over the years....everyone was kicking them to the curb to buy Demons, Holley HP, etc. Oddly enough many Buick GS guys sold me their old Carter Comps for a song. Now they bring a lot more just for a core. The float bowls are on the sides, not in the middle like a Qjet.
