| Selecting the correct manifold for your Small Block Chevy application. We offer a number of manifolds for small block Chevys and for some people, it may be confusing trying to figure out which one is the best for a specific application. The following information should be helpful in allowing you to make an informed decision. All of these manifolds will fit up through model years 1995 due to our unique included adapters. | CYCLONE™- The Cyclone is our lowest profile SB Chevy manifold and is also the only one that is street legal on pollution controlled vehicles. It is set up to accept a spread bore carb but comes with an adapter plate that permits the use of square bore carbs. To remain street legal with a square bore carb, you must use one that is also approved as street legal for your application. This is our largest selling manifold with tens of thousands of them in use. |  | This manifold is available in 8 configurations:
52000 - Polished for std heads
52001 - Satin for standard heads
52002 - RealChrome for std heads
52003 - RealChrome/Vortec heads
52006 - Polished for Vortec heads
52007 - Satin for Vortec heads
52008 - Polished w/EGR provision
52009 - Satin w/EGR provision These are great all-around street manifolds for mild performance applications at affordable prices. |
| CYCLONE+PLUS™- The terrific Cyclone+Plus is a step up from the Cyclone. Due to its slightly taller height, it can provide more power and torque. It is about 3/8" taller than the Cyclone. It also has a rear water crossover, the only SB Chevy manifold made by anyone with this feature, nitrous bosses and a square bore carburetor flange. It comes in versions with or without intake gaskets, a tube of gasket sealer, 12-point stainless bolts, and alll necessary pipe plugs. |  | There are six part numbers:
52010 - Polished with complete kit
52011 - Satin with complete kit
52012 - Polished w/o kit
52013 - Satin w/o kit
52014 - RealChrome w/kit
52016 - RealChrome w/o kit
A great medium performance manifold that includes all the latest manifold technology for the street.

| TYPHOON™- The Typhoon manifolds, along with the similar CrossWind, are the most powerful dual plane manifolds available for a small block Chevy. For non-pollution controlled street machines, these are among the very best manifolds you can use. They feature a square bore carburetor flange, nitrous bosses, four corner water ports, and dual distributor holddowns. These manifolds are approximately 5/8" taller than the Cyclone series. On medium horsepower engines, dyno tests have shown that this manifold comes very close to producing similar power and torque numbers as our Hurricane racing intake manifold. |  | There are three part numbers in this series:
52020 - Polished finish
52021 - Satin finish
52022 - RealChrome finish |
| CROSSWIND™- The CrossWind design features the identical plenum and runner design as the Typhoon. The main difference is that there is an open area under the plenum chamber. This feature is sometimes called an air gap design. The air flowing under the plenum provides a cooler charge for the incoming air with less heat transfer from the engine. This cooler air charge provides additional power. The CrossWind design is very popular. However, if looks is your main interest, along with more power, the Typhoon might be a better choice because it is impractical to polish the open area below the plenum on the CrossWind. |  | 52025 - Polished finish
52026 - Satin finish RealChrome is not available on this manifold due to the difficulty in polishing under the plenum. |
| HURRICANE™, HURRICANE+PLUS™, & SUPER HURRICANE™ - We now offer three models of this outstanding racing manifold. The Hurricane is one of our very most popular race manifolds. If you are looking for the utmost performance for the very least cost, this is your manifold. The base Hurricane is a terrific manifold for budget engines such as claimer motors. An improved version of the Hurricane is the Hurricane+Plus which, like the Hurricane, is designed for 400 to 550 hp engines under 400 cubic inches. The Hurricane+Plus, new for 2008, will make about 12 to 15 more hp than the Hurricane on a similar engine. For all out racing with large cubic inch engines (420+) on gas, or any size alcohol engine, the Super Hurricane is the manifold to select. Dyno tests have shown significant power increases over competitive manifolds. The Super Hurricane is also available in a version with machined injector bosses. |  | 52030 - Polished Hurricane
