The Edelbrock Super Victor LS3 #2826 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. They also feature tapered runners for increased flow at high rpm. A carburetor mounted style throttle bracket is recommended.
