The factory unsilenced air cleaner assemblies drew air from above the block. The most common design is the '68-69 non-fresh air assembly used on Road Runners, Formula S Barracudas, etc. They are still available from Mopar Performance (or whatever they are called these days), but would look a little out of place on an Imperial. And yes, flipping the air cleaner lid is an old, old trick. Used to be that most cars in a high school parking lot had the lid flipped. Can't do that with a modern car though. Rob McCall '67 LeBaron -----Original Message----- You can get similar effects by drilling holes in the bottom of the original air cleaner housing OUTSIDE the outer edge of the filter element for a stock look but better breathing. You're getting warmer air from atop the block, but the snorkel is getting warm air from the radiator anyway, so as a shade-tree thing goes, it's not too bad, I guess. I left mine stock. ----------------- http://www.imperialclub.com ----------------- This message was sent to you by the Imperial Mailing List.
