Engine Gasket Set - SBM 318-340

The FEL-PRO Engine Gasket Set 260-1121 is a comprehensive full gasket kit engineered for small block Mopar 318-340 cubic inch engines. This complete kit provides all the gaskets and seals required for a professional engine rebuild or overhaul, eliminating the need to source individual components and ensuring compatibility across the entire engine block. FEL-PRO is the OEM-equivalent gasket supplier trusted by engine builders and transmission shops nationwide for precision-fit gaskets that maintain proper sealing under high-temperature and high-pressure operating conditions.

This 260-1121 gasket set covers the critical sealing points throughout the small block Mopar engine platform: cylinder head gaskets, intake and exhaust manifold gaskets, valley pan cover seals, fuel pump gasket, timing cover gaskets, and oil pan seals. Each component is manufactured to OEM tolerances and material specifications, ensuring leak-free assembly after rebuild. The kit's comprehensive coverage eliminates guesswork during disassembly and reassembly, reducing the risk of post-rebuild leaks that compromise engine performance and longevity. Weighing 2.6 lbs and compactly dimensioned, the complete kit ships efficiently and organizes easily on the workbench.

This gasket set serves engine rebuilders, performance shops, and dedicated DIY enthusiasts restoring 318 or 340 cubic inch small block Mopar engines—whether for classic muscle cars, truck restoration projects, or crate engine installations. The 318-340 platform remains popular in vintage Dodge, Plymouth, and Chrysler applications, and proper gasket selection is essential for achieving reliable startup and long-term sealing integrity. By purchasing the complete FEL-PRO kit rather than individual gaskets, builders reduce sourcing delays and ensure all sealing components meet the same engineering standards.
