Big Block Headers for GM Sub Frame 1967-1969 F Body


These headers designed for Speedtech Performance specifically for ’67-69 Camaros and Firebirds using Big Block engines in a GM sub frame with a factory style steering box.

Made from 304 Stainless Steel, these 1 7/8″, .065 wall CNC mandrel bent primary tubes fit perfectly without requiring dimpling for steering linkage clearance. These headers clear the steering box however they do require that you remove the box, install the headers, and reinstall the box. Their long tube design provides awesome low end torque and street performance with decent ground clearance. Internal Merge Spike collector technology promotes a more directional exhaust flow for better scavenging, increased power, and improved sound. CNC laser cut flanges means an accurate fit while slip fit 3 1/2″ OD collectors provide an easy to work with seal. Available in satin Mill Finish or mirror like Show Polish Finish. Gaskets and fasteners not included. May not work with factory A/C components.

Integrated Merge Spike Technology

Increased Power

Too much air resistance or back-pressure can make it difficult for the cylinders to expel exhaust, restricting an engine’s power. Merge Spikes help reduce turbulence which means less back-pressure, allowing your engine to unleash more power.

Better Scavenging

Inspired by race-system technology and backed by performance dyno testing, the Merge Spike was developed to direct airflow towards the center of the collector, which helps promote scavenging.

Improved Sound

The other benefits of creating a more directional airflow is that the turbulence within the collector is reduced, improving performance and generating a purer sound.
