DESCRIPTION

 

OEM 1977-78 Pontiac Trans Am Pontiac W72 L78 400 Shaker Air Cleaner. The assembly has been refinished in semi-gloss black to present a period correct image. The base features the round snorkel inlet in good condition with the correct 4" opening, OEM yellow-striped vacuum lines, and a new heavy duty air filter. Both an original ATS with correct clip and EVE valve with clip are included as well. The exterior features a GM Licensed Air Cleaner Service Decal (RD=77). The base features the correct deep drop required for proper shaker hood clearance, as well as the angled flange that parallels the base level with the sloped hood line of the F-body. The assembly connects to your fresh air system if desired.


An original shaker lid installs on top of the filter to provide the correct airflow to the assembly. To complete the package, a period correct wing nut and a new filter breather replete with GM stamped ribbed rubber adapter are included. 


This assembly is in nice condition and will enhance your restoration. Best of all, it is a genuine GM part!

APPLICATIONS

 

This assembly is correct for the following 1977-78 models:

Pontiac

Trans Am with 400 Pontiac engine: W-72 (77 specific due to 4" round snorkel inlet); L78 400.

Note: 78-79 W-72 cars came with the oval snorkel inlet - this assembly will still work, but is not technically correct.


*It will also fit 455 Pontiac engines transplanted into 400 cars. 

 

Note: this will NOT fit the L80 403 Olds engines or Pontiac 301/Chevrolet 350 engines due to the offset of the shaker scoop, as well as the difference in carburetor flange drop. 

  

FITMENT

 

The assembly will fit factory 4 barrel Quadrajet carburetors with a 5 1/8" diameter flange, as well as Holley (it will NOT fit double pumpers; i.e. models 4150/4160), Carter/Edelbrock variations without an electric choke (some adjustment to the carburetor alignment tangs may be required). If you have modified your carburetor or intake manifold, please inquire first prior to bidding to ensure fitment is correct. Return requests for non-fitment will not be honored.
