LS Exhaust Header for 1961-1962 Corvette Radiator and Manual Trans
When swapping an LS powerplant into a 1961-1962 Corvette with manual transmission the original cooling setup often falls short of shedding heat under heavy use. This 1961-1962 Corvette Radiator with Fan (Manual Trans) addresses that gap by fitting exactly into the stock core support while making room for steering linkages and the custom LS exhaust header assembly. With an aluminum core that uses a dual pass design and high density fins it moves heat away from the block more efficiently than the original unit. Built with a low profile fan shroud that aligns to factory mounting bosses and an integrated cooler circuit for the manual trans it offers reliable performance without modification and preserves underhood clearance for tight engine bay installations.
Precision Mandrel Bends for Optimized Exhaust Scavenging
The 1.875 inch mid length primary tubes employ mandrel bends that maintain a smooth inner surface, minimizing turbulence and backpressure as exhaust gases exit the combustion chamber. By matching tube diameter to the LS engine's pulse timing, these bends sharpen throttle response and improve low-end torque delivery. Laser cut and jig welded flanges guarantee perfect port alignment and a leak free seal, while the headers' close fit to frame rails preserves essential underhood space for steering linkages and accessory brackets.
Ceramic Coating for Effective Heat Management
A silver ceramic coat forms a thermal barrier that reflects radiant heat away from the firewall, wiring harnesses and fluid lines. This finish can lower temperatures under the hood by up to fifty degrees Fahrenheit, protecting sensitive electronics and reducing the risk of hose and connector failure. In addition to heat control, the coating seals the steel surface against moisture and road debris, limiting corrosion and helping the headers retain their shape and performance through repeated thermal cycles.
Robust Steel Construction for Long-Term Durability
Fabricated from 16 gauge cold rolled steel, these headers resist warping and cracking even after extended high-temperature operation. The thicker wall section dampens vibration, yielding a cleaner exhaust tone and preventing noisy resonance. Steel's rigidity ensures the flanges remain square to the head ports, maintaining a consistent seal as the engine heats and cools. Reinforced tube geometry also stands up to road impacts and abrasion beneath rocker panels, delivering reliable service life on street and track.
Seamless Installation with Factory Boss Alignment
Engineered to bolt directly to the LS block and existing frame bosses on 1988–1998 two wheel drive GM trucks, these headers eliminate the need for cutting or welding to chassis components. Included high-grade gaskets and bolts create a uniform seal from the first startup, while detailed instructions guide each step of the process. The tube contours are designed to clear steering assemblies, coolant lines and alternator brackets, saving installation time and preserving service access in tight engine bay layouts.
Engineered for a direct fit and consistent performance under demanding driving conditions.
