    Edelbrock 28084 - Edelbrock Big Victor Spread-Port Manifolds Details

    For use with Brodix Big Duke Heads Only

    Designed for large cubic-inch or high rpm drag racing Big Block Chevy combinations, these manifolds have an average runner area of approximately 4.75 sq.in. The port exits have .090" per side reduction to accommodate the wide variety of intake port sizes and require port matching to the head being used. The runners have a minimum corner radius of .500" from the plenum to the exit allowing the popular oval port shape to be used. The outside runners are shorter and straighter than competitor's manifolds and the plenum is longer front to back. These features, combined with approximately 5% taper in runner cross-sectional area, give better top end horsepower while maintaining consistency and throttle response off the stop

    Designed for large cubic-inch or high rpm drag racing big-blocks with Big Duke Cylinder heads, the Big Victor Spread-Port manifold makes more horsepower than any other single-quad intake. We've heard from top racers and engine builders all around the country and the consensus is that the Edelbrock Big Victor Spread-Port manifold makes from 20 to 35 horsepower more than their previous manifold. One well-known racer even got a 50 horsepower increase after porting his new Big Victor intake. Top end horsepower is improved while maintaining consistency and response off the throttle stop.
