Description

1975 1976 73 74 75 76 PONTIAC TRANS AM 400 455 SHAKER AIR CLEANER BASE . Condition is Used.
This is a complete original GM shaker scoop air cleaner assembly from a 1976 Pontiac Trans Am with a 455 engine and 4 speed transmission.  It with fit all 73 74 75 76 77 78 and 79 model Trans Ams but has the emmisions control components for the 1975-1976 models so it has an extra hole in the side if you plan to use on a 73 or 74 model and will need one added for a 77 78 or 79 model, however all geometry and dimensions are the same from 73-79. Except W72 1977-1979 has crankcase fliter hole in 9 o'clock positions instead of 8 o'clock like this one has.
This is an all GM  factory original air cleaner assembly complete with lid (which was professionally powder coated) , Therm AC components, perfect 6 inch air snorkle, shaker scoop stainless steel clamp ring,  vacuum hose clips, and pre heat hose elbow.   This is an original surivor piece in amazingly solid, unrestored and unmodified condition!! Not all cut up and no holes have been added.  Has some very light surface rust and survivor  quality 40 year old original paint but its rock solid and complete,  even still has the original vacuum hose clips on the bottom. Would only need  beadblasted,primered and painted for any showcar quality application.  Please view all of the pictures to see how nice this very rare air cleaner assembly is. Was factory installed on a 1976 Pontiac Trans Am with the 455 Pontiac engine.  It is rock solid with no major rot, pin holes, nothing except  light surface rust peeling paint and some scratches from use and storage. The inner bottom actually has areas of clean bare metal showing, how amazingly rare is that???   These are commonly advertised incorrectly so rest assured this one is 100 % correct for the rare 1975 1976 models and would only need a hole added to side for 1977 78 and 1979 models 400 and standard 455 as well as 455 HO  400 engines either 4 speed or automatic transmission. It will also fit earlier 1973 and 1974 400 and 455 models but will have extra holes for emmissions devices etc.
This air cleaner base is rock solid on the bottom not soft from rust out.  Has all bottom vacuum line clips still intact. Has the correct pre heat hose elbow GM part number 498539 with the original Wittek clamp. Snorkle is in great  condition with no dents or rust and integrated flapper door moves freely and all Therm AC components are intact, clean and hold vacuum while functioning properly.  Correct factory GM  original domed lid is also in excellent condition and was powder coated at the cost of 0.  Included is a new correct style air filter element. And even has a correct  used breather element.
This unit is CORRECT for the shaker hood scoop as it has the deep drop base necessary for hood to scoop clearance. Has the correct 6 inch snorkle for maximum air flow and performance. Has the front hole for the carburetor bowl vent tube. Base has Correct angled flange to parallel the sloped Trans Am hood. Has correct 5 1/8 inch QUADRAJET round opening. Correct relief on back side of base for distributor clearance. And all correct rock solid vacuum line clips factory spot welded on underside of base. If your shopping around for a shaker scoop air cleaner assembly make sure ALL of these are present because they are NECESSARY for any Trans Am shaker scoop to work. Without these you WILL have major problems including your hood not shutting and damaging your hood scoop. BEWARE as many are incorrectly advertised.
These  air cleaner assemblies are extremely difficult to find as most rotted out quickly. The geometry is pretty much the same for the 1973-1979 air cleaner bases, emmissions devices were added after 1974.
This will NOT fit any Trans Ams equipped with the 403 Oldsmobile or 301 Pontiac engine. Will NOT fit any Chevrolet engine.
Finding one of these air cleaner assemblies is nearly impossible finding one not rotted out, complete and fully functional with a pristine unmodified snorkle just doesn't happen anymore. As cool and iconic as the shaker scoop was on the Trans Am, the seal leaked and the air cleaner held water,  they rusted out quickly. Even when found 25 years ago the bottoms were rotted or soft from rust.  If you need one for a 1975 or 1976 Pontiac Trans Am 400 or 455  in excellent, unmodified condition now is probably your LAST chance.
Not reproduced by anyone, and NEVER are found for sale these days. Nice solid complete original shaker scoop air cleaner base assembly here. Perfect one to restore for a showcar quality appearance.
