SBC Headers - 67-81 Truck

The SBC Headers - 67-81 Truck are a street-performance header set engineered specifically for small-block Chevy engine swaps in GM full-size trucks and SUVs. This pair delivers improved exhaust scavenging and horsepower gains over factory cast-iron manifolds through optimized primary tube diameter and a 3-inch collector design.

Built from heavy-gauge steel with a black paint finish, these headers arrive complete with gaskets and mounting hardware, ready for bolt-on installation without additional fabrication or fitment work. The 1.625-inch primary tubes are sized to balance scavenging efficiency across the small-block Chevy's RPM range, maximizing mid-range torque while supporting higher-RPM power production typical of street and mild performance builds.

This header set is purpose-built for truck owners and engine-swap enthusiasts upgrading 1967–1981 full-size GM trucks and SUVs with small-block Chevy engines. Whether pursuing a restomod build, replacing worn-out manifolds, or maximizing streetable performance without turbocharging or forced induction complexity, these headers deliver exceptional performance.
