Engine Gasket Set - BBC 66-79 Competiton Series

The FEL-PRO Engine Gasket Set — BBC 66-79 Competition Series (part number 260-3015) is a complete full-engine gasket kit engineered for big-block Chevy applications from 1966 through 1979. Built specifically for high-performance and competition use, this gasket set delivers the sealing integrity and thermal stability demanded by serious engine builders and mechanics preparing vehicles for track duty, high-horsepower builds, and sustained performance driving.

FEL-PRO's Competition Series gaskets are formulated to withstand the elevated combustion pressures and temperatures generated by modified big-block Chevy engines. The complete kit covers all critical sealing points—cylinder head gaskets, intake manifold, oil pan, timing cover, and auxiliary components—eliminating the need for multiple partial orders. Competition-grade gasket materials resist blow-out and degradation under sustained high RPM and boost conditions, making this set the preferred choice for rebuilds targeting consistent cylinder pressure and leak-free operation across extended engine running periods.

This gasket set is specified for engine overhauls on BBC (big-block Chevy) platforms including the 396, 402, 427, and 454 cubic-inch variants commonly found in muscle cars, trucks, and performance builds. Whether replacing worn seals during a full rebuild, upgrading from factory gaskets to competition-grade materials, or assembling a high-output engine package, the FEL-PRO 260-3015 provides the comprehensive coverage and reliability expected in professional machine shops and serious performance garages. The kit eliminates guesswork and ensures all mating surfaces receive matched, purpose-built gasket material in a single purchase.
