We stand behind our LT swap longtube headers in saying you will not find a better fitting, quality built, budget header for your vehicle.

• CNC Machined Flanges

Vehicles:

• 1960-1987 C10 Trucks
• (1960-1966 C10 Trucks require slider engine mounts to clear the front crossmember)
• 1960-1987 K10 Trucks

Note: Headers do not hang below the frame and offer ground clearance with air ride suspension and lowered suspension. Customers have installed this product on Choppin Block, Roadster Shop (with Pro spindles), Porterbuilt, and other front drop members with air ride and coil over suspension.

Note: “Due to older vehicle frame clearance headers are pulled in very tight, and require our LT spark plug wires”.

Note: “For LT Direct Injected series engine swaps only” These do not work on standard SBC or BBC engines.

Note: Installed pictures are of our 1 7/8″ headers with 1″ offset back motor mounts.

Note: If using a larger 4L80E or older Turbo 350/400 transmission the bellhousing ears may need to be trimmed for proper clearance.

Note: Can fit 4wd applications with proper engine position and custom exhaust work. Having lifted suspension is a plus for driveline clearance. 

Note: Might require oil cooler adapter or delete kit on the LT4 engines.

Note: 1963-1972 C10 Exhaust system is also designed to work with our trailing arm crossmember. If the factory crossmember is used holes will need to be cut in order for our exhaust to pass through.
