How to Install a 440 Intake Manifold Gasket
Introduced in 1966, the Chrysler 440 was the last production V8 engine that the company released in its RB big block series. In its earlier years, this engine had a power output of 375 brake horsepower. But by 1972, emissions regulations drastically increased the performance of the Chrysler 440. The intake and exhaust system was changed due to these regulations, therefore cleaner-burning engine parts were being used. Production of this engine halted in 1978, giving all models the antique classification. The intake manifold gasket will eventually need to be replaced to conform to factory specifics.

Removal
-
1
Loosen the bolt that holds the negative connector of the engine's battery to disarm all electrical flow. Keep the bolt in a safe place for reconnection after installation of the gasket is complete.
-
2
Remove the wingnut that holds the air filter box together. The air filter box is located on top of the engine block. Removing it will expose the intake manifold and attached parts.

-
3
Tag the individual wires to the respective spark plugs they connect to. Pull the boot of the spark plug wires to remove them from the plugs.
-
4
Remove the distributor cap to access the rotor below. Wiggle the rotor until it points straight ahead. Make a note of how this corresponds with the distributor. Detach the clamp that holds the distributor into place and remove this part.
-
5
Disconnect the vacuum hoses and electrical wiring that link the intake manifold to the corresponding exhaust and powering parts. If necessary, tag these wires and hoses to avoid any confusion when reinstalling.
-
6
Loosen the bolts that hold the factory intake manifold into place. Once all have been removed, lift the intake manifold from its place on the engine block. Place the mounting hardware and manifold to the side for later use.
-
7
Pry the intake manifold gasket from its surface with a flathead screwdriver. Scrub the surface of the engine block with engine degreaser and a linen cloth until thoroughly clean.
Installation
-
8
Coat both sides of the new intake manifold gasket with chemical sealer to bond this part to the engine block. Position the new intake manifold gasket on top of the cylinder flanges of the engine block until all holes completely align.
-
9
Place the old intake manifold on top of the newly-installed manifold gasket. Make sure all of the holes of the manifold line up with the manifold gasket and cylinder ports.
-
10
Attach all of the bolts of the intake manifold loosely into place. Once all have been set in their respective holes, tighten the bolts. Torque these bolts with 25 foot-pounds of pressure to accurately secure.
-
11
Replace the distributor at 20 degrees counter-clockwise from where it is needed to rest. Turn until you reach the intended position. Replace the distributor cap.
-
12
Reconnect all hoses and electrical wiring that were removed earlier. Pull the boot of the spark plug wires over their corresponding spark plugs. Attach the negative connection of the 440's battery by bolting the connector back into place.
