Intake Manifold Components

Mopar Performance intake valley pan set for all big blocks. Set includes the steel valley pan and steel heat crossover block-off plates. Note: The block-off plates are used to stop the exhaust gases from running under the manifold in order to keep the manifold cooler (keeping the air/fuel mixture cooler and giving the engine more power). But if the plates are used, engine warmup will take longer and the automatic choke will not function properly.

Accurate Reproductions located on the underside of 340 & 360 intake manifolds. Each include the correct drive screws for proper installation. Keeps the hot engine oil off the center of the intake manifold.

Bet you didn't know your 361, 383, 426W, or 440 engine originally had noise insulation between the intake manifold and the pan! Used on ALL VERSIONS of these engines, silencer package #1879-747 is two pieces of fiberglass insulation wrapped in tinfoil, as original. It is POSSIBLE to install these exactly reproduced pieces after your manifold is already in place, but it's much easier to do like the factory did. They were placed on the pan, large piece in front, small piece in rear, then the manifold was bolted in. These pieces should have engine paint overspray

Excellent reproductions of the vacuum control connectors used on the intake manifolds of cars WITHOUT power brakes. Machined with the details of originals with 3/8" NPT threads and silver cadmium plated as originals.
