Item # PP-52012
This polished manifold is our top-of-the-line medium profile street performance. It is similar to our 52000/52001 Cyclone, 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. This is an outstanding performance street manifold and represents current state-of-the-art technology in intake manifold design for small block Chevy engines using the popular 23 cylinder heads. This manifold features an integral rear water crossover passage. This is the only small block Chevy manifold currently in production with this feature. RPM range Idle to 5500.
Manifold only. No gaskets or bolts supplied.
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.
