Description

Put the look of the dual carburetor muscle car era on your late model Chevrolet LS Series engine. Holley LS 2x4 dual plane carbureted intake manifolds continue the tradition of the great Holley 4160 induction systems that competed on the drag strips. Their dual plane, equal-distribution layout produces great midrange torque without compromising top-end power. The manifolds feature all cast aluminum construction, a wide 1,500 to 7,000 rpm power band range, and can accept dual inline mounted square bore carburetors with 1 11/16 in. maximum diameter throttle bores.
