I fell into a casual conversation with one of my brothers about Mopar options and stuff..

..and since Shakers look so cool, we got to thinking about the question.

Any idea why Ma Mopar limited the Shaker option to the E-bodies? ..were they only offered in '70 and '71?

Was it a marketing decision?
Maybe the Shaker wasn't in high enough demand to expand its offering?
Maybe something physical, like clearance in the engine bay?
Too expensive in a shrinking market?

Anyone know or care to guess?

There was a company that was making retrofit shakers, was looking seriously into putting one onto my volare.
It's been several years since I saw these listed, as I remember they were even catered specific to f bodies for some reason, they were slightly scaled down in size.

The a-bodies were a budget cars so that might explain those not having anything other than basic hood scoops. If you fancy up your low line car too much it may steal away sales from the other more expensive cars as well?

Not sure a shaker would look good on a B-body car? I guess I'd have to see one to make the call.

The 70 RR airgrabber is not a shaker setup, but I think it's better looking.

Anyone remember the aftermarket durango shaker set ups?

The E-bodies were new for '70, so......maybe to draw attention to the new model? The A-bodies and B-bodies already had their own hood treatments. Maybe...I dunno...just a geuss

Question for the shaker hood E-body guys, was the shaker centered left and right through the hood and was the engine centered in the engine compartment too?

Want to say the shaker base plate that seals to the bottom of the hood is the part that is offset. This is from memory of looking at them at cars shows.

The baseplate adapter ring has the offset.

years ago at the mopar nationals, a seen a mercedes with a shaker hood set up. didn't look to bad. maybe some one here has a pic

Probably the same reason Air Grabbers were not offered on E bodies. Each had it's own unique designs.

There was a write-up about that Benz in Mopar Action so might be in the archives
I like the Cobra Jet shaker hoods on the big Fords they look good

Thanks guys, I was thinking the centering of the shaker might have been one of the reasons but sure doesn't look like that had anything to do with it, Some may not have noticed the offset of the air cleaner to the Air Grabber and the A12 hood underside versus the centered hood scoop but I guess that was never a problem for air intake/air filter/hood scoop location. The only thing that was ever (to my knowledge) a problem with a hood and hood scoop was told to me back in the '90's by Dick Maxwell regarding the lack of a method to close off the A12 scoop and take air in from a safe area inside the engine compartment like other Mopars and all of the other manufactures. This is what Dick Maxwell told me and I swear that it is true. In order to put a lift-off-hood on the A12 with no hood hinges and that if would not be necessary to disconnect any kind of a hood scoop intake closing system every time you removed the hood. He had to prove "to upper management" that the A12 could survive and stay running in wet or snowy weather. So he had the help of two other engineers and put an A12 on rear wheel rollers, put removable corner drain openings in the air filter tray and ran the A12 at half throttle on the rollers for nearly 30 minutes as he and one other engineer "hosed" the A12 hood with garden hoses in the mist pattern. Dick said that he convinced upper management that no one would ever drive a car with this much power at anything over half throttle in the RAIN OR SNOW. As we now know he convinced management to allow the LOH with no way to close off the hood scoop opening other than stuffing foam or a rag in it (suggested on labeling) to go into production, No other Mopar or any other manufacture has done that to this day that I know of? Ah the good old engineering days of Mopar and the Ramchargers

The Shaker debuted in 1969 on the Mustang, and it was available through 1970. With the redesigned Torino for 1970, it was available through 1971. Pontiac introduced it with the Trans Am mid-year 1970 and was used through 1983, I think.

When the Mustang was redesigned for 1971, Ford used NACA ducting for air induction.

So if it was such an interesting and popular form of gimmickry, why did Ford discontinue it? Maybe because it was a gimmick, and there were more sophisticated ways to convey speed? And maybe Ma Mopar felt the same thing when the 1971 B-body was introduced?

Another reason to think about is that 1972 was a year when performance was dead. The Shaker was just too much of a fussy item to deal with, and I know Pontiac had issues with new emissions rules and eventually make it non-functional, which would have been easy to do with a hood that was already standard on a model.....?

What emission issue would there be?

Well, I may have used "emissions" loosely, but I believe there was a noise issue with the engine.

Pure speculation but the later part of your statement make the most sense IMO. 72 is when you started seeing things being standardized across multiple car lines. The side markers were changed to a generic design that could be used on many different vehicles. That change alone had to save the company a lot of money. E-body door handles were also standardized. Hood pins, flip top gas caps and spoilers were gone in 72 as well. That's a lot less "fussy" items to deal with. Limiting the available options really saves the company money and makes things flow more smoothly on the assembly line. In 73 even more things were standardized. The E-body grills/header panels and tail light panels were carried over from 72. The fender mounted turn signals were changed to a generic design that was put on most of the other car models. The Challenger even used the Cuda vinyl top starting in 73.

All valid and good points by Burdar.
Although Ford beat Chrysler with the release of their shaker hood in 1969,
Chrysler began development of their shaker hood system earlier than Ford.
Even the oval air cleaner for use on B-bodies was being developed in December 1967 for future use.
The complexities of the E-body shaker hood itself and its understructure was likely enough in itself to forget development for use on an A or B-body
Mechanics hated working on shaker equipped cars...having to remove all that system just even for simple carb(s) adjustment.
