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: Would require adjustable motor mounts with 1" offset back.

Note: "Does not fit 4wd"

Note: This product with off road x pipe kit will need a modified or aftermarket crossmember for fitment on installation. This kit will work with Suspension Engineering transmission crossmember with required shims (4L60 will need 3 shims).
