BB Mopar Intake Gaskets 361-383-400..1961-78

The FEL-PRO BB Mopar Intake Gaskets for 361-383-400 engines (1961-78) are essential sealing components for anyone rebuilding or restoring a classic Chrysler B-Series big-block engine. These valley pan gaskets sit between the intake manifold and cylinder head, preventing coolant and oil leakage in one of the most critical high-pressure zones of the engine. Whether you're performing a full engine rebuild, replacing worn gaskets after decades of service, or upgrading an aging muscle car, quality intake gaskets directly impact reliability and longevity.

Manufactured by FEL-PRO, a trusted OEM gasket supplier, the BB Mopar Intake Gaskets feature embossed metal construction with a precise 0.015-inch thickness engineered for optimal compression and sealing performance. The rectangular port design measures 1.230 x 2.270 inches, conforming exactly to Mopar B-Series specifications. This embossed metal construction provides superior durability compared to paper or composite gaskets, resisting deformation under the thermal cycling and pressure that big-block engines produce. The gasket set ensures proper sealing without requiring excessive torque, reducing the risk of head bolt stretch or manifold warping during installation.

Restoration enthusiasts and engine builders working on 361, 383, or 400 cubic-inch Mopar motors between 1961 and 1978 will find these gaskets indispensable for achieving a leak-free, professional-quality rebuild. Installation requires standard gasket surface preparation—thorough cleaning of both manifold and head surfaces to ensure full contact and seal integrity. The compact package weighs just 1.65 pounds and fits standard gasket shipping dimensions, making it convenient to stock for multiple projects or to keep on hand during a long-term restoration. Pairing these intake gaskets with quality head gaskets and timing cover seals ensures your vintage Mopar block will perform reliably for years to come.
