Edelbrock Part # 2826 Super Victor LS3 carbureted intake manifold is designed for Gen IV LS engines equipped with LS3 cylinder heads. This new Super Victor intake manifold is ideal for anyone building a 700+ hp 4150 series carbureted large displacement racing engine operating between 3,500 - 7,500 rpm. This new Super Victor intake manifold is designed with 24% larger runners than our Victor Jr. #28457 along with a larger 4500 style plenum. The large plenum makes this intake manifold ideal for nitrous and forced induction applications. This intake manifold also features tapered runners for increased flow at high rpm. A carburetor mounted style throttle bracket is recommended.
