408 original air cleaner dimensions, please?

David No One Seems Willing To Help Possibly Because You Have A Non Original Motor That May Be Different To The Original. I Will Pass On My Experience With My 411 And 412. The 411 Came With A Standard Air Cleaner With The Standard Cast Iron Manifold Which Holds A Lot Of Heat. I Decided To Replace The Manifold With A Second Hand Alloy Holley Manifold. Great Until I Fitted The Original Air Cleaner And Discovered The Bonnet Would Not Close. I Note You Motor Appears To Have An Alloy Manifold.the Standard 408 Air Cleaner Is Quite Large Which Could Causes The Front Of The Air Cleaner To Hit The Bonnet So You Need To Check Closely Your Measurements.

In The Short Term I Found A Standard Round Air Cleaner With A Lowered Base Plate Which Gave Me The Clearance I Needed. Later On I Had The Top Of The Manifold Machined Down About 1/2 An Inch And I Can Now Just Close The Bonnet .

The Original Air Cleaner Certainly Reduced The Intake Noise Quite A Bit. All This May Not Apply To A 408.
