LS Swap Longtube Headers 1 7/8" 304 Stainless

The Speed Engineering LS Swap longtube headers are specifically designed to facilitate the installation of newer LS series engines into 1967-1969 Camaros and 1968-1974 Novas. Constructed from durable 304 stainless steel, these headers feature mandrel-bent tubing for optimal flow and a natural stainless steel finish. The primaries measure a full 1 7/8" and are port-matched, leading into a 3" collector. These headers are compatible with a wide range of LS engines, including 4.8L, 5.3L, 6.0L, 6.2L, LS1, LS2, LS3, LS6, and LSA. Engineered for performance and affordability, these longtube headers have been dyno proven to provide gains of over 25 rwhp. They feature CNC machined flanges for precise fitment and come with standard graphite manifold gaskets. The product note specifies that these headers do not bolt up to older SBC or BBC engines. Additionally, for installations using a larger 4L80E or older Turbo 350/400 transmission, the bellhousing ears may require trimming for adequate clearance. Vehicle applications include the 1967-1969 Chevrolet Camaro, 1968-1974 Chevrolet Nova, and 1967-1969 Pontiac Firebird. It is important to note that this product is designated as RACE ONLY and is intended solely for competition purposes. Installation of this part means the vehicle may no longer be used, registered, or licensed for use on public roads or highways, and doing so may violate the Clean Air Act and incur personal liability.
