GM 350 Intake Manifold Bolts Torque Specificationsby Anne Davis
The 350 is a member of Chevrolet's small block engine family. First built in 1967, this 5.7-liter engine is featured in such vehicles as the Chevrolet Camaro and Nova. Throughout its life, the 350 has had numerous models identified by letter combinations such as L-48 and LT-1. Regardless of the model, the intake manifold has the same torque specifications.
In an internal combustion engine, the intake manifold supplies a mixture of air and fuel to the cylinders. An even distribution of this mixture ensures the engine can operate at peak efficiency. Typically, the intake manifold is constructed from aluminum or cast iron.
