L82 Air Cleaner Help.
Hey Guys.
I was been searching the internet for a few days now trying to find out what involved in replacing the factory air intake in my 78 L82 with one of the round chrome style ones that everyone seems to have. I really can't find any info.
What is involved in replacing it? I thought it would jut bolt on but I am noticing there is some kind of sensor in the old style snorkel and there are 2 hoses and a vacuum line going from the factory air cleaner. one hose on each side goes into the headers and one goes into the back of the carb.
What I am wondering is what do I do with the stuff that is attached to the factory snorkle.
Is there a how to on how to install the nice style round ones?

Needless-to-say, with all of the underhood heat in the engine compartment of the later model C3's, there is a real advantage to the factory "cold" air intake.

Actually the dual snorkel assembly seems to be an excellent cold air intake more than adequate for the engine.
Here's how the factory system works.
Both of the snorkels have a vacuum motor operated damper. In the bottom of the air cleaner is a thermostatic vacuum switch that closes with heat.
The vacuum connection is at the base of the carburetor.
With a cold engine at low speed both dampers are closed by vacuum. When closed, the front damper switches intake air to the "heat stove" on the driver side exhaust manifold via the connection and tube (often missing) at the bottom of the snorkel. The side snorkel is directly connected to the vacuum source.
As the engine warms the thermostatic vacuum switch closes which in turns opens the front snorkel damper allowing cold air intake.
During periods of heavy acceleration, vacuum from the carburetor base drops and the side snorkel damper opens.
From what I've seen people will pay FAR more for one of those original dual snorkel intakes than the cost of a chrome thing that doesn't even provide cold (ambient) air without a hood scoop.
