i have a 3 inch tall 14" round with a drop base. the intake mainfold makes a difference also. different manifolds have different hights.
which manifold are you running? also which hood? that makes a difference... mine used to clear the grabber hood with a 2" tall then i put on the performer rpm and had to go to a 1" tall to clear the hood.
performer 289 intake 1" spacer, Holley 4160 14x3.75" KNN air cleaner with drop base. cleared fine on mine!
would this work? i have a performer 289 intake 4 barrel holley carb http://www.summitracing.com/parts/SUM-G3001/?rtype=10 any recommendations?
i ran a performer 289/ holley 4160 and a regular non-drop base 14x3" air cleaner and it cleared fine . If you can cough up a little more money i'd go with this one: http://www.summitracing.com/parts/TFS-23021/
