Rpm Air Gap Fit With Holley Street Avenger

like bbeep71 said you'll need a drop base air cleaner.

with the 3310/1850 style carb and the short air cleaner element and a solid top you will have air flow restriction that will lead to a lean condition when the secondaries crack on.

if you're running a carb that doesn't have a choke tower you'll be fine, otherwise i'd suggest switching to a K&N open element top.

also, you'll only be able to fit a 2" filter element.
