We get excited by tri-power set-ups like this one on Bob Rawlings' '65 Hi-Po fastback. These are Holley 200cfm two-barrel carburetors atop a Buddy Bar intake. The center primary carburetor is different than the two secondaries. Although we tend to see them as the ultimate in induction systems, they don't always deliver the performance expected. However, they're great eyewash at any car show.
