Three individual Rochester 2G carburetors were arranged inline on the intake manifold, the center one operating normally and the outer two acting as secondaries, or "dumpers", for full throttle performance. Tri-Power often included a hood bulge to accommodate the carburetor set-up and identifying badging on the vehicle's exterior.
Tri-Power as original equipment on classic Pontiacs often raises their value today. Oldsmobile, Chevrolet, Chrysler, and Ford also offered a three two-barrel option, popularly referred to as "Tri power", "tri-power" and related variations of the Pontiac term.
