52000 Cyclone (non-EGR) - Polished
52001 Cyclone (non-EGR) - Satin
 The 52000/52001 Power + Plus Cyclone Manifold is a direct replacement for the stock manifold on 1957-'95 Small Block Chevy non-EGR engines. Includes special adapter bushings to fit '87-'95 engines. Use the stock Quadra-Jet carb or 500-650 cfm vacuum secondary carburetor. Kit includes adapter plate to permit use of certain square bore style carburetors. Power + Plus Manifolds are cast from tell molds, not from sand molds. Permanent molds provide a tighter grain casting thereby reducing the occurrence of porosity which can mar the polished finish. Additionally, each Power+Plus Manifold is 100% pressure tested for leaks to eliminate installation problems. This is our most popular manifold and is showing up on many performance street machines and street rods.
The 52000/52001 manifold is a stock replacement/street legal part for 302, 327, and 350 V8s with OEM carb or Edelbrock #1400 carb; 1966-72 (1973 non-CA) passenger cars, 1966-83 trucks and Suburbans, except stock equipped EGR.

52010 Cyclone+Plus for 23 Degrees Heads - Polished
52011 Cyclone+Plus for 23 Degrees Heads - Satin
 This is our top-of-the-line medium profile street performance manifold. It is similar to our 52010/52011 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 is also supplied with a quality intake gasket set, 12-point stainless tell attachment bolts, stainless washers, and a full complement of aluminum pipe plugs to plug unused tapped holes. We even include a tube of Permatex Ultra-Black silicone sealer for use on the two ends of the manifold where it seals to the block.
This manifold will typically produce ore power then any similar competitive manifold due to larger ports and runners.
