trying to ID intake. Mopar used Thermoquads on the 340 starting in 1971. The part number is not correct for the 72 340. 360 4v engines also used the TQ and the E48 (318 4v) used a Quadrajet. The Carter Thermoquad and the Rochester Quadrajet are the only carburetors to have the large secondaries that would work on that manifold without some sort of adapter plate.
