Edelbrock Victor Series Manifolds For B/B Chevy Spread-Port


CHEVROLET 396-502 V8
BIG VICTOR SPREAD-PORT (3500-8500 RPM)
Designed for large cubic-inch or high rpm drag racing big-blocks with Edelbrock Big Victor, Dart Big Chief or Brodix Big Duke cylinder heads, 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. 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 crosssectional area, give better top end horsepower while maintaining consistency and throttle response off the stop.

Big Victor High-Rise intake manifolds are based on our popular Big Victor designs, but have been modified to meet the needs of custom porting specialists. The casting has added material on the top of the runner and exterior area of the carb pad. This gives engine builders the extra material they need to apply custom porting without welding.

Big Victor 2 intake manifolds go one step further. They have the same outer dimensions as the Big Victor High-Rise, but also have an extended runner design, carb pad and plenum for increased air flow and performance in large displacement race engines. These intake manifolds are designed to perform right out-of-the-box with minimum modifications, but can still be ported as needed. Port matching is required for best results. All applications are equipped with a 4500 Series flange and will accept 2.25" throttle body butterflies without a spacer or modification.

BIG VICTOR 2 CNC SPREAD-PORT (3500-8500 RPM)
Edelbrock Big Victor 2 CNC intake manifolds are designed for large cubic-inch or high rpm drag racing big-blocks. They are a spread-port design and have been CNC port matched for a proper fit right-out-ofthe- box, when used with the Edelbrock Big Victor, Dart or Profiler Raptor cylinder heads.

These manifolds have the same features as the standard as-cast Edelbrock Big Victor 2 Spread-Port intakes. All applications are equipped with a 4500 Series flange and will accept 2.25" throttle body butterflies without a spacer or modification. They are available for short- and tall-deck applications.

BV3 CNC (3500-8500 RPM)
These manifolds are designed and have been CNC port matched for use with Edelbrock BV3 cylinder heads which feature a unique symmetrical port layout for the 4.84" or 5.0" bore spacing big-block Chevrolet applications. These new manifolds feature a spider style single-plane design with efficient runners that are engineered to deliver peak performance across a wide range of applications. They have a lengthened plenum and a narrowed runner design to deliver equal length runners.

These new manifolds are also the first in the Big Victor Series to feature Edelbrock's unique two-piece design. This unique design simplifies and reduces time in applications that require CNC porting. The manifolds are cast in two separate pieces, allowing them to be taken apart for better porting access and then they can bolted back together while maintaining a perfect match. Each piece has a precision machined o-ring groove to ensure a proper seal. High quality bolts and washers are supplied. Each manifold also has a matching valley plate with the proper flange thickness. These unique valley plates feature an highly efficient integrated water distribution system, reducing the need for external plumbing. All of these manifolds feature a carb pad with a 4500 Series flange that is also large enough to accommodate various throttle body and throttle stop applications on the market today.

BIG VICTOR HV SPREAD-PORT (3500-8500 RPM)
Big Victor HV manifolds are identical to our #2801 and #2802 intakes, but with a smaller plenum and smaller velocity runners for optimal performance on engines with a displacement up to 590 cubic inches, or for larger displacement engines whose power band is primarily below 6500 rpm. This combo makes this an ideal choice for throttle stop applications or for custom ported versions to create unique port configurations.
