52020 Typhoon for 23 Gegrees Heads - Polished
52021 Typhoon for 23 Gegrees Heads - Satin
The Power+Plus Typhoon Manifold is a high performance dual plane, 180 degrees street manifold designed to be used with Holley, Carter AFB, or Edelbrock square bore carbs. For street applications use 600-700 cfm vacuum secondary carbs. For high performance street, use 700-800 cfm double pumper carburetors.
This manifold produces power comparable to some single plane manifolds yet retains the throttle response and drive ability typical of a dual plane. This manifold also features cast-in nitrous bosses with water outlets at all four corners plus dual distributors' holddowns.
This manifold is .70-inches taller than the #52000 or #52001. It has a provision to add an oil fill tube. Non provision for exhaust heated or stock style chokes. Accepts late model waterneck, A/C, alternator, and HEI. Will fit cast iron bow tie heads and '87-'95 cast iron or aluminum heads. Will not fit under a stock Vette hood.
Note: This manifold is not legal for sale or use on any pollution controlled motor vehicle.

52025 CrossWind for 23 Degrees Heads - Polished
52026 CrossWind for 23 Degrees Heads - Satin
The new CrossWind Manifold is a special version of the 52020/52021. While it is the exact same height, it features an open area under the plenum chamber. This provides for a flow of cooling air which keeps the temperature of the air/fuel charge lower thus producing more power and torque. The interior plenum and port design are identical to the 52020/52021 and will provide somewhat better overall power than the 52020/52021 due to the special design.
Note: This manifold is not legal for sale or use on any pollution controlled motor vehicle.

52027 CrossWind for Vortec Heads - Polished
52028 CrossWind for Vortec Heads - Satin
The Power+Plus CrossWind for the Vortec features the same plenum and runner design as our popular 52020/52021 and 52025/52026 manifolds. In this design the manifold is made wider to accommodate the Vortec design heads and also features the Vortec port configuration. The manifold also has a square bore carb pad to utilize the standard Holley, Carter and Edelbrock carburetors. This manifold is intended for use on up through '95 blocks using the 1996 and later Vortec (Gen 1+) heads or Edelbrock E-Tec heads. It can also be used on '96 and later Vortec engines with some minor modifications.
This manifold will typically produce ore power then any similar competitive manifold due to larger ports and runners.
