Mopar 440 Big Block Intake Manifold Gasket 1966-1978 Speedmaster PCE349.1023

Speedmaster intake manifold gasket set for the Mopar 440 Big Block (1966-1978). Listed for one application: Mopar 440 Big Block engines, 1966-1978, in Dodge, Plymouth, Chrysler applications. Confirm your engine code and year against this listing before ordering.

What it does

The intake gaskets seal the manifold to the heads (and on older engines, the coolant crossover too). A collapsed gasket leaks vacuum and sets lean codes; on a wet-manifold engine it leaks coolant into the valley. A new set restores a sealed intake tract.
