HVH Super Sucker Carburetor Adapters
Get your carburetor mounted properly using one of these HVH Super Sucker carburetor adapters. Common knowledge and experience tell us that open spacers help top-end power, and 4-hole spacers help midrange power. Now, the best of both worlds have been merged into one with these adapters. Compromises are minimized, so it's no longer necessary to sacrifice one portion of the power band to increase another. The unique transitionary blend between the 4-hole ports at the base of the carburetor and the open plenum of the intake manifold has provided tangible gains in both midrange and high-rpm power.
