1971-72 CHEVROLET CHEVELLE GMC SS SPRINT COWL INDUCTION AIR CLEANER 396 400 402 454 LS5 LS3
DESCRIPTION
OEM 1971-72 Chevrolet Chevelle/El Camino SS/ GMC Sprint LS3 396 400 402 LS5 454 ZL2 Cowl Induction Air Cleaner. This assembly has been refinished in the correct semi-gloss black finish to present a period correct image. The single canted snorkel with round end is in nice condition and correct for the last of the LS-engined Cowl Induction platforms. The base is very clean and adorned with a new GM Air Cleaner Service Decal (DH) and new white-striped vacuum hose. Note that the snorkel is canted downward and is angled towards the corner of the passenger side fender (71-72 specific). It is also unique to these years as well, incorporating the ThermAC pre-heater function that was required for the new emissions standards as of 71. The original flame arrestor tube is topped with a very nice original GM stamped stainless screen, all connected to the valve cover with a GM stamped adapter hose on the bottom connector tube. The ThermAC connects to the AC Air Temperature Sensor with new white-striped vacuum hose and is secured with an original GM clip. An original style date stamp has been added for further authenticity and as a nice finishing touch. A nice original pre-heater elbow, replete with Wittek Tower screw clamp and a correct black aluminum pre-heater flex hose is included to make installation more complete.
The cowl induction flange is fitted with a very nice original survivor seal (not glued on) along with a new REAR decal. The original air cleaner lid enhances the classic muscle car appearance and is installed with a period correct wing nut. To add further distinction, a choice of either a GM licensed 454/365HP, 396/300HP, 400/300HP Silver and Black Turbo-Jet, or Multi-colored Invader decals are available (temporarily installed - permanent installation to be made upon purchase) and complements the overall assembly; please let us know your preference. Note that the 72 models did not feature an engine/horsepower displacement decal - it is included as a personal preference to use or not.
As an added value, a reproduction A212CW square mesh air filter - replete with correct lettering - is included to make the assembly appear as it did when new.
This assembly presents well and will enhance your restoration. Best of all, it is a very rare and genuine GM part!
Several companies will try to pass off the 70 style reproduction cowl assembly as correct for 71-72 models - this is not the case. These were specifically designed to meet more stringent drive-by noise regulations, as well as be emissions compliant. While the aftermarket pieces are "affordable," they are far from correct and can be distinguished from originals in a fraction of a second when one knows what to look for.
Many of our parts are available only once - we cannot predict if/when another will become available due to the scarcity of original parts. The old adage "here today, gone tomorrow" applies to many of these unique assemblies. While we strive to maintain a strong diversity of desirable parts, there simply aren't enough available to meet demand at times.

APPLICATIONS
This assembly is correct for the following:
1971-72 CHEVROLET
454/365 & 396/300HP & 400/300HP or 402/300HP Turbo-Jet models installed in Chevelle SS/El Camino SS cars featuring the Cowl Induction ZL2 option.
1971-72 GMC
Sprint with LS3/LS5 engine options with ZL2 option (uses INVADER 454 decal)
Note: both automatic and 4 speed equipped cars featured the ThermAC valve on the top of the snorkel. Non-cowl induction cars used a smaller case single/dual snorkel air cleaner specific to these years depending upon the A/C option. These assemblies differed from the 1970 version with the incorporation of the new for 71 ThermAC emissions provision for heated air at start-up using the air temperature sensor. The snorkel was canted downward, as opposed to the 70 straight version.
For the 72 version, no displacement decal was used; we will include one so you may choose to add it for more eye appeal if desired (loosely installed).
FITMENT
The assembly will fit factory 4 barrel Quadrajet carburetors with a 5 1/8" diameter flange, as well as some Holley (factory), Carter, and Edelbrock variations without electric choke (some adjustment to the carburetor alignment tangs may be required).
