The Edelbrock Super Victor LS3 carbureted intake manifold is built for Gen IV LS engines with LS3 cylinder heads and is targeted at 700+ hp 4500-series carbureted large-displacement race engines operating roughly between 3,500–7,500 rpm. It features runners 24% larger than the Victor Jr., a larger plenum suited to nitrous or forced-induction use, tapered runners for high-rpm flow, and accommodation for bores up to 2.25" with a recommended carburetor-mounted throttle bracket.
