The Chevrolet Performance LS long block is a premier choice for enthusiasts seeking a high-performance engine upgrade or a robust foundation for custom builds. Engineered with proven Gen III and Gen IV small-block technology, introduced by General Motors in 1997, this long block delivers exceptional horsepower and a broad torque band, ideal for retrofitting older LS-equipped vehicles or powering new projects. Its advanced design, featuring high-flow rectangular cylinder head intake ports from Gen IV LS3 engines, outperforms earlier Gen III intake ports, ensuring superior efficiency and power. Compatible with 1997–2006 Gen III small-block V8 engines, it uses a 24X crankshaft trigger and 1X camshaft trigger system, allowing seamless integration with existing sensors, exhaust systems, and engine mounts. The long block supports fuel injection and accommodates both stock and custom induction components, offering unmatched flexibility.
Enhance your LS engine with premium upgrade components designed for performance, durability, and style. A high-quality aluminum timing cover from Speedway Motors provides a lightweight, durable upgrade with a sleek aesthetic, available in black, raw, or polished finishes. Two-piece cast aluminum valve covers, designed for GM LS-based engines, hide ignition coils (Delco 510C and D580 styles) for a clean look, with provisions for mounting and a baffled ventilation system. A CNC-machined 92mm throttle body with a fabricated intake manifold maximizes airflow for mid-to-high horsepower LSX engines, featuring a 4-bolt pattern, drive-by-cable design, and progressive throttle control for consistent response. High-performance V-band cast iron exhaust manifolds, compatible with 2002–2012 LS engines (LS1, LS2, LS3, 4.8L, 5.3L, 6.0L), optimize exhaust flow and simplify installation with included clamps and hardware.
Elevate your LS engine’s appearance and performance with the All American Billet Silverline Series serpentine kit, designed to deliver an aggressive black style with machined finish highlights for a standout look. This kit includes high-performance components such as an aluminum water pump, a black 180 Amp 1-wire alternator, a black peanut-style A/C compressor, a black aluminum Type II power steering pump, a Silverline Series power steering reservoir, a tensioner with an aluminum cover, a Fluidampr harmonic balancer, 6061-T6 aluminum pulleys and brackets, a Gates 6-groove belt, and stainless steel hardware.
