Edelbrock part #28009 Big Victor 2 CNC intake manifold is designed for large cubic-inch or high rpm drag racing big-blocks. The Big Victor 2 is a spread-port design and has been CNC port matched for a proper fit right-out of-the-box, when used with the Edelbrock Big Victor, Brodix, Dart or Pro-Filer Raptor cylinder heads. This manifold has the same features as the standard as-cast Edelbrock Big Victor 2 Spread- Port intakes. This intake manifold is equipped with a 4500 Series flange and will accept 2.25" throttle body butterflies without a spacer or modification.
