Maybe trying an offset base will help with clearance. You may not need the spacers. If I understand correctly this idea may help.Ongoing efforts to fit a 14 inch aftermarket air cleaner with filtered top into 15 inch opening in Ram Air plenum. I have a 460 with Weiand Stealth high-rise intake, so there isn't enough room for stock type air cleaner. Removed about 3/8 inch of laminated alternating aluminum spacers and gaskets under carb to increase total vertical space available.
Now dropped air cleaner base sits flush on reinforcement bar between shock towers (expected that..). Ordered 1/4" and 1/2" aluminum air cleaner base spacers because underside of filtered air cleaner top also hits Holley 750 air horns and can't have base sitting on shock tower cross brace either.
Obviously using either of those base spacers will reduce vertical space available again, so can't use 14 x 3 inch filter and trying to fit 14x2 filter instead (which is why the dropped base results in carb top interference with filtered top steel underside).
Have a Performer 460 intake still in the box too and I am sure that would simplify vertical space issues, but really want to keep the Weiand on it. So, not giving up on adapting to that intake yet.
Standard aftermarket air cleaner top appears that it would fit better than filtered (thicker) top on both carb top clearance and underside of hood structure, but not sure that the 14 x 2 inch side filter can draw enough air under higher RPM (probably not over 4500-5000). Forgot what cam is in the motor, but think it was Lunati 268H. Trans is CJ big spline Toploader and rear is 3.55:1.
Any air flow guru's have any ideas about whether I would have sufficient air flow with 14 x 2 inch filter and a solid air cleaner top, as opposed to the filtered top that would seem to alleviate any potential restricted air flow issues (but is considerably more difficult to squeeze into the limited space) ?

Check this picture of my engine. The lower picture is with a 14" filter, a 1" carb spacer, the stock cover and the offset Spectre base.
