Speedmaster PCE147.1099 Fits Chevy SBC 350 Holeshot +Plus 1957-95 Intake Manifold Ceramic Coated

This is our top-of-the-line medium profile Holeshot Plus Series manifold. It is similar to our PCE147.1001 Holeshot, although slightly taller, but with several important modifications. First, it has a square bore carb flange instead of a spread bore. The square bore flange permits direct bolt-on of all popular Holley, Edelbrock, Carter, and Demon carburetors. This manifold is also the only SB Chevy manifold available that features a built-in rear water crossover passage. This typically will provide for better overall water flow and cooler engine operating temperatures. It also features nitrous bosses, and rear water ports. This manifold will typically produce more power than any similar competitive manifold due to larger ports and runners. NOTE: Manifolds will not work on engines with reverse flow heads as utilized on 1992-'96 LT-1 Corvette or 1993-'97 LT1 Camaro, Firebird, Caprice, Impala or Roadmaster.
