on a side note, If anyone is looking for a smaller air cleaner there is one listed on ebag now. It clears the underhood frames on A-bodies and show a lot more of your 6-packs and intake.

Mopar Tri Power Mr Norm 440 Air Cleaner #300263972064 Buy-it-now $400

Last spring I bought mine for $250+shipping and no air filter. Saw a few around at car swap/shows for $250-350 this summer.
This is the kind that Mr. Norm put on 340 GS Demons (not 440, if I'm reading the Ebag ad right.)
