64-77 Chevelle Header w/LS Engine

The 64-77 Chevelle Header with LS Engine from HEDMAN is designed specifically for enthusiasts converting classic A-body platforms to modern LS powerplants. This header is ideal for those restoring a Chevelle SS or building a street/strip machine, addressing the critical challenge of routing exhaust from a contemporary engine into a chassis originally designed for small-block or big-block Chevrolet engines.

Constructed from mandrel-bent primary tubes, this header maintains consistent wall thickness and minimizes exhaust gas turbulence, which is essential for maximizing power and spool time in turbocharged or supercharged LS applications. The collector design directs spent gases smoothly into a 2.5-inch outlet, effectively reducing backpressure and accommodating both naturally aspirated and boosted configurations.

With a weight of 19.54 lbs, this assembly balances durability with weight savings, crucial for vintage muscle car builds where every pound affects handling and acceleration. The compact profile fits within the tight engine bay constraints of first- and second-generation Chevelles, preventing interference with A/C, power steering, and factory brake lines that often remain in restorations.
