    I run the Performer with the air induction. It works. I'm using a different seal, though- the wheel well rubber for a C4 Vette. It's more pliable than the factory air induction seal.

    Check my webpage.

    I also notice that's a Mustang base, will the factory base and lid work?

    I've run one on my '77 Camaro with no problems. It fits just fine.

    What???

    That's a 3rd Gen L69 (5.0l HO) air cleaner base. It has the same exact vertical dimension as the factory 1980 air cleaner. I have interchanged them a few times without issue.

    Todd, I bought the whole 5.0/HO assembly (base, lid, hoses, and snorkels) only to find that it won't work with my long AC pump. The options are to either change over my whole Ac system or "manufacture" a new one using an old single-snorkle base and a cutting wheel.

    I believe that the air-cleaner base assemblies for the air-induction hoods were basically the same as the non-air inductions pieces. The differnce was the filter size and lid diameter.

    Any help?

    Todd,

    I just got the inner fender seal from the Vette to use on my air-induction air cleaner. That is a PERFECT seal for the job. It's a bit thinner than the original so you can pick up a little clearance. It's also much more pliable than my 25 yr old cracked rubber seal.

    The original seal had flattened out so much that it was blocking a substantial amount of airflow. The new "Vette" seal is much better. All I had to do is cut off a few inches and glue it together with 3M weatherstripping glue.

    For those who are interested, the GM part number is #14104943. It is about $20.

    Thanks Todd.

    I had a performer with a demon carb with a 3 1/2 filter on my 81Z. I had to cut the metal under the hood to close it. so if you run a shoter cleaner it should be ok
