§ DESCRIPTION: Edelbrock Air Cleaner Assemblies - Due to the many different applications of the Edelbrock air
filters, some modifications maybe required. The part numbers listed above with asterisks (*) come with a crankcase
ventilation adapter.

INSTALLATION INSTRUCTIONS

Note: Some Air cleaner kits include the crankcase ventilation adapter, that adapts to the lower side of the air cleaner per
the recess seen in figure #1 (Crankcase ventilation adapter #1205). Other kits may not be applicable.

1. If you wish to use the crankcase ventilation hose fitting, drill two ¼” bolt holes (A) in the recessed area at the rear

of the air cleaner base, then drill several ¼” holes (B) in the larger recess to allow the fitting to breath
(See figure #1). Bolt the fitting to the base with the ¼” nuts, bolts, and washers. Be sure to de-burr drilled holes.

2. Install air horn gasket and carburetor stud on the carburetor and place air cleaner base over carburetor.

3. Install filter and air cleaner lid with wing nut. Check for clearance between the carburetor stud and hood before

closing hood. Trim carburetor stud as needed.
