The KH2-TGM Holley Tri-Power rebuild kit is engineered for GM applications using the factory triple two-barrel Holley carburettor arrangement found on 1967 to 1969 Corvettes. These high-performance 400 and 435 HP engines featured a dedicated centre carburettor supplying primary metering, with the outer carburettors functioning as vacuum-operated secondaries. This kit includes the correct gaskets, needle and seat assemblies, pump diaphragms and seals required to restore all three units to proper operating condition. It provides precise coverage for Holley List numbers 3659, 3660, 3888, 4055, 4055-1, 4056 and 4056-1, ensuring an accurate and reliable rebuild for both stock restoration and ongoing drivability.
