LS Intake Manifold for 1953-1998 GM Corvettes Vans G-Body Trucks A/B/F Bodies
Swapping an LS engine into a 1953 through 1998 Corvette, G Body or GM truck often means wrestling with tight packaging and heat soak. This LS intake manifold is designed to preserve runner geometry and airflow without requiring trimming of frame rails or steering components. Constructed from silicon molybdenum ductile iron, it holds precise runner shape through repeated heat cycles and resists warping under loads that support up to 500 horsepower. Complete with OEM style gaskets, matched bolts and flanges, this direct fit solution installs on Chevrolet blocks without modification and streamlines your swap process.
Silicon Moly Ductile Iron Structure Delivers Heat Endurance
Crafted from a silicon molybdenum enriched ductile iron alloy, this intake manifold resists the thermal strain of repeated high temperature cycles common to LS swaps. Its robust material composition maintains precise runner geometry and flat sealing surfaces under extended heat exposure, reducing the risk of warping or cracking over time. The natural cast iron surface provides an ideal base for an optional ceramic coating that guards against corrosion in harsh environments. By preserving structural integrity through daily driving and spirited sessions, the manifold ensures consistent performance without premature fatigue. This fundamental durability supports power levels up to 500 horsepower without compromise.
Tight Tuck Runner Profile Optimizes Fit in Classic Chassis
The carefully contoured runner layout hugs the engine block to preserve vital clearance in confined engine bays of 1953 through 1998 Corvettes, G Body coupes and GM trucks. This tight tuck design avoids interference with frame rails, steering links and exhaust components, eliminating the need for trimming or modification of the chassis. Installers benefit from a streamlined retrofit that respects original frame geometry and minimizes fabrication time. Internal transitions flow smoothly into a 2.25 inch outlet that sustains exhaust velocity for reliable scavenging. This balance of compact packaging and functional capacity makes the unit ideal for classic GM applications.
Refined Runner Geometry Enhances Airflow and Torque Response
Engineers optimized the internal passages to support strong mid range torque and efficient breathing under heavy load. The manifold maintains high exhaust velocity into the converter, promoting quicker light up and improved emissions control. By balancing runner length and diameter, the design fosters a broad torque curve across the entire rpm range without sacrificing top end output. Users will notice sharper throttle response and a more immediate power delivery in both street and track use. The flow characteristics also aid in maximizing the potential of up to 500 horsepower on upgraded LS engines.
Complete Direct Fit Hardware Kit Simplifies Swap Process
Each manifold kit includes OEM style gaskets, precisely machined flanges, matched bolts and rust resistant studs to ensure a leak free seal from the first installation. This comprehensive hardware collection removes the need to source components from multiple suppliers and avoids the risk of mismatched parts. Bolt patterns align perfectly with Chevrolet blocks, allowing technicians to focus on final tuning rather than chasing fasteners. The inclusion of durable welding flanges also provides a secure mounting point for downstream exhaust connections. As a result, installers can complete the retrofit in fewer steps and with greater confidence in long term reliability.
Engineered for a precise direct fit and lasting performance in your LS swap project.
