We offer the LS364/450 exclusively as a long-block assembly, without the induction system, ignition system, or front-end accessory drive system, allowing builders to transfer components from their early LS-powered vehicle or complete a custom build with the components of their choice. An intake manifold that matches the LS3/L92-style rectangular intake ports is required.
