304-401 AMC Exhaust Gskt 1970-1979

The 304-401 AMC Exhaust Gasket 1970-1979 is a crucial sealing component specifically designed for AMC's mid-range V8 engines during the classic muscle car era. This gasket is essential for those rebuilding or restoring vehicles like the Javelin, AMX, Rebel, or Hornet with a 304 or 401 cubic-inch block, as it prevents exhaust leaks at the manifold-to-head interface.

A compromised or aged exhaust gasket can lead to hot gases escaping outside the manifold, which reduces back-pressure and can mask true engine performance. The gasket is made from high-quality materials engineered to withstand continuous thermal cycling, as AMC V8s can reach temperatures between 350°F to 400°F at the manifold interface without degrading or warping. This design accommodates both the 304 (5.0L) and the 401 (6.6L) engines, ensuring reliable sealing across the exhaust port faces.

Restorers, hot-rodders, and daily-driver enthusiasts will find this gasket invaluable during overhauls of 1970–1979 AMC vehicles. Its precise dimensions ensure proper bolt clamping force distribution, preserving head gasket integrity and preventing cross-leak contamination between oil and exhaust passages. With FEL-PRO's OEM-quality engineering, this gasket is a dependable choice for maintaining performance in vintage AMC engines.
