LS Intake Manifold for 1953-1998 Chevy Corvette G-Body B-Body & GM Trucks
When transplanting an LS engine into a 1953 through 1998 Corvette, G Body, B Body or GM truck, airflow efficiency and heat management emerge as critical factors for both performance and longevity in confined engine bays. Crafted from silicon molybdenum ductile iron, this LS Intake Manifold maintains precise runner geometry under repeated high temperature cycles while its tight tuck profile preserves essential clearance around narrow frame rails and steering links. Complete with OEM style gaskets, bolts and flanges, the design bolts directly to Chevrolet blocks without grinding or trimming, eliminating compatibility headaches on mid century Corvettes and late model G Bodies.
Ductile Iron Construction for Superior Heat Resilience
These exhaust manifolds are cast from a silicon molybdenum enriched ductile iron alloy engineered to withstand the extreme heat cycles inherent in LS engine swaps. The alloy composition maintains precise runner shape and flat sealing surfaces under sustained thermal stress, ensuring consistent performance without cracking or warping. This inherent toughness translates into reliable operation during both daily driving and extended track sessions. The natural cast finish offers a sturdy base for an optional protective coating that guards against rust in corrosive environments. By preserving structural integrity over time, these manifolds minimize the need for costly replacements.
Compact Runner Layout Preserving Classic Frame Clearance
The tight tuck configuration brings the exhaust runners close to the block, maximizing space in narrow engine bays of 1953–1998 Chevy Corvettes, G Body coupes and GM trucks. This compact design preserves vital clearance between frame rails, steering links and suspension components without sacrificing exhaust capacity. Internally, the runners converge smoothly into a 2.25 inch outlet that sustains high exhaust velocity for effective scavenging. The result is balanced flow dynamics that improve torque response across the rpm range. Installers can rely on this layout to fit classic chassis without grinding or trimming surrounding elements.
Integrated Hardware Kit Streamlining Installation
Each pair of manifolds ships with OEM style gaskets, matched bolts, studs and durable welding flanges precisely machined to factory dimensions. This comprehensive hardware kit eliminates the risk of mismatched components and the need to source parts from multiple suppliers. Precise bolt patterns align perfectly with Chevrolet blocks, ensuring a leak free seal from the first bolt turn. The inclusion of all necessary fasteners and flanges allows installers to complete the retrofit in fewer steps, saving valuable time on the workbench. As a result, technicians can focus on tuning and final adjustments rather than chasing missing items.
Enhanced Flow Dynamics Supporting High Output
Engineers refined the internal geometry of these manifolds to support power levels up to 500 horsepower by balancing runner diameter and length for optimal flow. The maintained exhaust velocity accelerates catalytic converter light up, improving emissions control and reducing warm up times. By minimizing backpressure, the design allows the LS engine to breathe more freely, boosting both peak horsepower and low speed torque. Drivers experience sharper throttle response and a broader torque curve in everyday driving. This thoughtful flow enhancement ensures dependable performance in both street and competition settings.
Engineered for a precise fit and reliable performance in your LS swap, this manifold preserves airflow and simplifies installation.
