These intakes were designed for Holley 2-barrel Pro-Jection systems. They're high-rise, dual-plane manifolds with an EGR provision, and their powerband ranges from idle to 6,000 rpm. With these manifolds, there is no need for manifold-to-TBI adapters. They come with an EGR valve mounting pad, an EGR valve gasket, coil, and A/C bracket mounting bosses, and a transmission and throttle cable bracket.
