Oval Antics
Since we were building a manifold similar to a small-block Trans-Am 302 cross ram, we decided to take a cue from the factory with a custom air cleaner instead of a pair of simple 6-inch air filters. The factory used an oval air cleaner assembly to cover both carburetors that looks retro, so we took that idea one step further with a custom billet lid with fins to match the PML valve covers. We started with a 21x10-inch template that we took to our pals at CAD/CAM Consulting in Newbury Park, California. Pete Jorgensen used a picture of the original GM filter assembly to create this slick, finned version of a Trans-Am air cleaner assembly. We are still working on some of the cool design factors so you will only get several small glimpses of it now. Make sure to tune in when we unveil our Retro-Tech 327 in an upcoming issue, you won't be disappointed.

Filter Building
A custom air cleaner housing isn't much good without a matching air filter. While we could have built the filter around an existing filter element, that takes all the fun out of having a custom filter. What we discovered is that K&N will build a custom air filter element for anyone if you have filter dimensions for your application. We followed along as K&N built two filter assemblies for our EZ-EFI–equipped cross ram.
