Series 1-7/8 Ceramic Coated LT Long Tube Headers for 1971-1976 B-Body Impala/Caprice
For enthusiasts tackling an LT swap in a 1971 to 1976 Impala or Caprice B Body chassis, these one and seven eighths inch diameter long tubes provide the precise alignment and heat containment required for smooth engine installation. Crafted with CNC cut flanges that match the LT port pattern, they ensure a tight fit and leak resistant seal against the cylinder heads. Multi layer ceramic coating traps radiant energy inside the tubes to lower underhood temperatures and protect nearby hoses and wiring. Included gaskets bolts and V band clamps mean every mounting part is on hand to simplify your project and maintain a tidy engine bay.
Advanced Ceramic Coating for Effective Heat Management
The multi layer ceramic finish on each mild steel tube reflects radiant energy back into the exhaust stream, preserving heat within the headers and maintaining optimal gas velocity for improved scavenging. By trapping thermal energy, underhood temperatures drop significantly, protecting adjacent hoses, wiring and intake components from premature aging. The rigid ceramic shell endures repeated heating cycles without cracking or flaking, ensuring consistent thermal control and prolonged component life.
Precision Machined Flanges Ensuring Leak Free Sealing
Each flange is CNC cut to match the LT port pattern on 1971 through 1976 Impala and Caprice heads, with a uniform thickness engineered to resist warping under high temperatures. This exact fit delivers full surface contact against the cylinder head, reducing exhaust leaks and eliminating the need for frequent retorques. In combination with the supplied composite gaskets and V band clamps, installers achieve a reliable seal that maintains steady backpressure and supports smooth performance under all driving conditions.
Mandrel Bent Tubing and Quality MIG Welds for Smooth Flow
The long tube headers feature mandrel bends that preserve a constant internal diameter, eliminating flow restrictions common in stamped or crush bent designs. Premium MIG welds join the primary tubes to the flanges with uniform penetration, creating seams that resist fatigue from repeated thermal expansion and contraction. This fabrication approach ensures unrestricted exhaust flow, structural integrity and a durable assembly capable of withstanding demanding street and track use.
Complete Hardware Package for Streamlined LT Swap
This header set arrives with composite gaskets, high grade bolts and precisely sized V band clamps, delivering every mounting component needed for an LT engine installation in a 1971–1976 B Body Impala or Caprice. By including all fasteners and seals, the kit reduces swap time and removes the risk of mismatched parts. Installers benefit from an organized engine bay and a simpler workflow, allowing them to focus on tuning and accessory integration rather than tracking down hardware.
Engineered for precise fit and reliable performance in your LT swap and built to endure repeated heat cycles.
