Info

The Speedway Motors Eliminator Manifold has all the same great features as the Qualifier Manifolds, but with the addition of an open space underneath the plenum chamber, commonly referred to as an "air gap" design. The gap underneath allows for a cooler air charge coming into the motor that results in a jump in performance and power. This style of intake manifold has become very popular over the years, as they are a proven design that puts the power to the ground! The Eliminator series is set up to run a standard square bore carb, as well as featuring nitrous bosses, four corner water ports and dual distributor tie downs. When looking for additional power, without sacrificing the streetability of your ride, look no further than the Eliminator Manifolds from Speedway Motors!

  • Dual-plane, 180° design provides good throttle response and low-speed torque
  • High-rise plenum improves approach angle into the heads, increasing top end without sacrificing bottom end
  • Air gap design keeps air/fuel charge cool, eliminates exhaust crossover plenum heat box
  • Partially machined plenum divider wall improves top end power by allowing both cylinder banks to draw from all 4 barrels of the carburetor
  • 1500-6500 RPM power band, with comparable horsepower to a single plane intake in that range (with significantly more torque)
  • 5.160" x 5.625" "square bore" flange works with typical Holley 4150/4160 and Edelbrock Performer-style carbs
  • Textured plenum floor keeps fuel droplets in suspension during the transition into runners, improving mixture quality
  • 4-corner 1/2"-14 NPT coolant ports for flexibility in mounting temp senders or racing-style rear coolant hoses to prevent hot spots
  • Features 3/8"-18 NPT vacuum port, standard 5/16"-18 NPT carburetor mounting holes, and 3/8"-16 NPT distributor clamp mounting holes
  • Dual distributor hold-downs make it easy to adjust timing from either side of the engine

Fits 1955-86 SBC engines and will also work with later 1987-95 SBC cylinder heads using the supplied adapter bushings for the center 4 mounting holes (which are drilled at a different angle on those heads).

Some parts are not legal for use in California or other states with similar laws/regulations
