The Super Hurricane is designed for large cubic inch engines. Many SB Chevys are being built today in the 421 to 430 cubic inch range yet racers are trying to run the same manifoldsthat were designed for 400 inches or less. Usually less. So if you have a big inch small block, or an alcohol engine of any size, you need to use a manifold that has been specifically designed for that type of engine. This manifold features a larger plenum and bigger runners. To our knowledge, there is no other 23° head intake manifold that has been specifically produced for big inch engines. Do not attempt to use this manifold on 350 to 400 inch engines as it will not make the same power as our Hurricane or Hurricane+Plus. This manifold has injector bosses and is available machined for injectors. Dyno tests show excellent results on injected engines even with the larger runners since the manifold runs dry.

Note: Use Professional Products 10608 Fuel Rail Kit with injected versions of this manifold.

Our single plane big block manifold is now available with Dominator (Holley 4500) carburetor flange. Dual distributor holddowns. Nitrous/injector bosses. Four corner water ports. Available with show polished or satin (unpolished) finish. Priced over $100 less than many similar competitive single plane intake manifolds. Fits big block Chevy rectangular port cylinder heads on standard deck blocks.

Note: Use Professional Products 10626 Fuel Rail Kit with injected versions of this manifold.

This manifold is designed for racing or serious street applications using stock cast-iron or aftermarket Windsor style cylinder heads. Includes bosses that can be drilled and tapped for nitrous. It features a rear water crossover passage along with four corner tapped water ports. Ports are 1.90” x 1.08” at the gasket flange and the manifold contains enough material to open ports to 2.10” x 1.25”. Use Professional Products intake gasket #54600 or Fel-Pro intake gasket #1250 or #1262. This manifold includes a 1/8-NPT vacuum port under the carb flange, a feature lacking in competitive manifolds of this type. Note that due to the port layout on small block Ford engines, a single plane manifold, such as this one, will typically be suitable for street use as long as the vehicle is not too heavy.

This is really a great new addition to our Ford lineup. This Hurricane manifold for 35 W engines offers many features not found in any similar manifold. It has a bridged rear water crossover passage that helps keep engine temps down. It also features injector/nitrous bosses as well as two extra tapped water ports at the back. It is available with the injector bosses machined for injectores and we also offer a set of fuel rails #10606 designed for this manifold as well as a complete fuel rail kit #10607, which includes our #10671 fuel pressure regulator. See Fuel Rail section for specifics. This manifold will accept all standard pattern square bore carburetors. It fits standard 351 W blocks with a 9.50” deck height. An ideal manifold for circle track or drag racing engines operating in the 3500 to 7500 rpm range. Also suitable for high performance street applications.

Note: Use Professional Products 10606 Fuel Rails or 10607 Fuel Rails Kit with injected versions of this manifold.

This is an outstanding high performance street manifold with all the latest manifold design refinements. It features a full open design under the plenum for maximum air circulation to help keep the incoming charge cool for premium power production. It features a spread bore carb flange for those of you who want to run the original Rochester carburetor and we also include a square bore adapter plate and gasket for those who desire a square bore (Holley, Edelbrock, Carter) carburetor. The manifold can be drilled and tapped for nitrous nozzles and is also available in versions with machined injector bosses.

Note: Use Professional Products 10618 Fuel Rail Kit with injected versions of this manifold.

We now offer this outstanding single plane manifold that will fit under all stock Pontiac hoods including the Trans Am "shaker" style model. Accepts a stock Quadrajet carburetor, but we also include an adapter and gasket for the popular square bore carbs. This manifold is designed to work with any cylinder head up to 300 CFM. It has no exhaust heat crossover passage. It includes injector bosses that can be machined for injectors or drilled and tapped for nitrous nozzles. As-cast ports are a match for standard Pontiac head ports. This manifold can be port matched to RA IV head ports. Check out our Harmonic Damper section for both high performance street as well as SFI-Spec race dampers for Pontiac applications.

This manifold was dyno developed by Pacific Performance in conjunction with porting expert Dave Bishop. www.pacificperformanceracing.com

This is the only high performance high rise dual plane manifold available for this engine. It features a number of unique enhancements. The CROSSWIND design which provides an air gap under the plenum helps cool the intake charge for maximum power production. It features a square bore carburetor pad which is an inch and a quarter taller than competitive dual plane manifolds which further enhances the power producing capabilities. The manifold can be drilled and tapped for nitrous nozzles and is also available in versions with machined injector bosses.

Note: Use Professional Products 10619 Fuel Rail Kit with injected versions of this manifold.
