Designed for Gen IV LS engines equipped with LS3 cylinder heads, these new Super Victor intake manifolds are ideal for anyone building a 700+ hp carbureted or EFI large displacement racing engine operating between 3,500 - 7,500 rpm.
These new Super Victor intake manifolds are designed with 24% larger runners than our Victor Jr. #28457 along with a larger 4500 style plenum. The large plenum makes these intake manifolds ideal for nitrous and forced induction applications. They also feature tapered runners for increased flow at high rpm. Available with a 4150 or 4500 series carburetor flange. The Super Victor 4500 series manifolds can accommodate bores up 2.25". Super Victor #28215 and #28265 include machined fuel injector bosses. A carburetor mounted style throttle bracket is recommended.
