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

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

Note: "For LS series engine swaps only" These do not work on standard SBC or BBC engines.

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

Note: Some modifications might be required on G body applications.
