The standard Performer intake is close to stock intake manifold height. The Performer RPM is about an inch taller. You may run into clearance problems with the RPM and 3" air cleaner. regardless of manifold, it would be wise to check hood clearance with modeling clay or Play-doh before you slam the hood shut on your new intake, carb, air cleaner. You may need to use a drop base air cleaner, if this is the case, then you will need some type of banjo fitting on the carb inlet to clear the drop base.
