    LS Classic Series ’63 Chevy Fuelie Intake Systems are designed to give your LS engine the look of GM’s second generation mechanical fuel injection system found in ’63 - ’65 Corvettes while using modern technology for ultimate performance.

    The systems are based on a cast aluminum, two-piece manifold, like the originals, which is made in the USA. The intake kits include billet aluminum fuel rails, all mounting hardware, and gaskets.

    The systems utilize GM LS3 OEM fuel injectors and GM four bolt, 92mm, drive-by-wire throttle body (not included) and are compatible with GM and aftermarket ECU’s and harnesses that support both drive-by-wire and speed density tuning. Manifold kits are available to work with Rectangular or Cathedral port LS cylinder heads.
