LS Engine Swap Header for 1963-1982 Chevy Corvette
When fitting an LS motor into a 1963-1982 Chevy Corvette chassis, this LS engine swap header addresses underhood temperature control and exhaust scavenging in a single precision engineered assembly. Opting for 1.875 inch primary tubes tuned to collector geometry yields a smooth midrange torque rise and that signature Corvette rumble while avoiding restrictive backpressure. By employing machined 0.375 inch flanges that align with GM mounting points, it installs without adapters and seals leak free right out of the box. Its ceramic heat barrier finish protects intake runners, wiring harnesses and coolant lines from radiant heat for reliable operation under road and track.
Optimized 1.875 Inch Primary Tubes for Balanced Flow and Torque
These headers feature 1.875 inch primary tubes tuned to achieve the ideal trade off between gas velocity and volume. That precise size smooths exhaust pulses as they converge in the collector, reducing restrictions that sap midrange performance while preserving full top end potential. Matched tube lengths and collector angles shape pulse timing into a more linear torque curve, amplifying the hallmark Corvette rumble without harsh drone. Drivers will notice more immediate throttle response through city streets and sustained pulling power when pushing the chassis on road or track. The tubes also serve as a thermal buffer, limiting heat migration into surrounding engine bay areas.
Robust Steel Build with Precision Machined Flanges
Constructed from heavy gauge steel, each primary tube and junction holds its form under repeated high temperature cycles and constant vibration. The 0.375 inch thick flanges are precision machined flat to align perfectly with GM head surfaces, delivering a uniform tight seal without the need for custom adaptors. This exact mating surface prevents exhaust gas leaks that can diminish output or damage adjacent components over time. With this stable interface in place, the header assembly maintains consistent performance across thousands of miles, making it suitable for daily driving and more demanding high speed runs.
Ceramic Coating for Under Hood Temperature Control
A ceramic barrier finish on each header tube inhibits radiant heat transfer from the exhaust path into the engine bay, reducing ambient under hood temperatures by as much as one third. Cooler bay conditions help protect sensitive parts such as wiring harnesses, coolant hoses and intake runners from premature ageing caused by excessive heat exposure. In addition, the thermal barrier retains denser intake charge temperatures for more efficient combustion and stable running under load. The tough abrasion resistant surface bonds through repeated heating cycles, ensuring the coating stays intact against road debris and corrosion.
Direct GM Fitment Streamlines LS Swap Projects
These headers bolt directly to GM mounting bosses on Corvette frames built between 1963 and 1982, eliminating adapter plates and custom fabrication. A complete gasket and hardware kit is included so installers can seal the exhaust system right away and avoid repeated sealant work. Exact port alignment guarantees a leak free interface from the first start and holds tight without constant retorque. The simplified installation not only cuts labor time but also ensures reliable exhaust flow dynamics on both street driving and track sessions.
