Selecting
the correct manifold for your Small Block Chevy application.
Professional Products offers a number of different
designs of manifolds to fit a variety of requirements.
While the descriptions and part numbers on this page
apply to small block Chevys, the general use description
for each style of manifold also applies to other types
of engines. Check out the various styles outlined below
to see which manifold design best fits your specific

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 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. |

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

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 all 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. |

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.

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.
