The green vacuum advance canister was part of the Cleaner Air Package for California cars; my '69 383 4-speed Calif Roadrunner had one, as did my '68 Charger 383 4-speed CA car. I don't remember it on my '68 383 auto Roadrunner that was bought new in Denver.
The '69 Charger R/T I posted isn't a California car. I don't think it's a Cali-thing..... Also, Carl's '69 is an unrestored car he bought off the original owner. He's had the car since I believe '76... So, it's definitely not a 4-speed thing either....

The green CAP valve was put on all 68-69 Hemi engines no matter which trans it had. There is a picture of a 68 HEMI GTX conv. in Car Life Feb. '68 road test that clearly shows the valve in place. I also have a picture of a NEW 68 Hemi Coronet R/T that was in a 68 vintage magazine that shows the crew replacing the fact dist with a Mallory unit and you can clearly see the CAP valve in the pictures. The mounting bracket is unique to hemi's, but you can use a valve from a 383/ slant 6 one and replace the bracket with a repro hemi one.
I agree..... I also see from the markings that the bracket was bolted in place, on the intake and painted with the motor. Then, the green valve was positioned and the "V" part of the bracket grimped around the valve...

I HAVE A NOS ONE IN A BOX WHICH IS GOING ON MY HEMI ROADRUNNER.it states that it is for both manual and automatic cars, they call it a USED CAR CLEANER AIR PACKAGE or vacuum advance control valve.
it states when the engine idling in nuetral adjust the idle speed at 650 for automatic cars and 700 rpms with manual transmission.
so now we are sure it is for both trans. carsit also is used on 6 cylinder cars as well 695rpm with auto.trans 745 rpm with manual.

"The green can thingy" and at least a dozen other names it has been given over the years... Time for another re-hash... same questions: 1) What years installed by factory? 2) Manual only, or both manual & automatic? 3) For all states?... Entire production run for each year? Any new info... I was told there were some recent articles in some Mopar magazines...??? Quote:
The green valve was also used on the '68 Hemi, both standard and automatic.
It has three nipples, one goes to manifold vacuum, one to the rear carb timed port and the other to the distributor. In normal operation the valve lets the vacuum advance work as usual but under the high vacuum of deceleration it routes full manifold vacuum to the distributor. Full advance during deceleration helps clean up emissions.
Here's one on my old '68 Hemi RR.

My 68 RR has its original green "thingy" back on and it seems to work OK. Second owner took it off when he raced the car but was a pack rat and kept everything - bonus for me... I've heard the usual stories from back in the day that those were usually tossed early on. The Factory Service Manual has instructions for testing/tuning and I seem to recall that mine was still operating as it should. These are some shots from several years ago when the motor was on the stand.
