differences in shakers?

[cuda hunter]

Are there difference's in the shakers?

I'm sure there are difference's in the lower pan from small block to big block.
Assuming there are different holes for the motor call outs.

But are there any other difference's I should be aware of?

Differences were limited to the base plate, based on whatever engine.  Those differences included number of carb openings and changes in the base throat height and the type of brackets required for the stabilizing "feet".

Scoop holes for emblems were uniform.  All shaker emblems had the three long studs that had the same spacing.  In other words, they were interchangeable.

I don't think there were any other differences beside scoop color.

[cuda hunter]

thanks.

So scoop colors would have been argent in 70, Red in early 70.   Dark argent in 71.  Correct?

[Floyd]

I'm no expert on scoop colors but black organisol was in the mix as well.  My early build 71 Challenger came with a black scoop.

thanks.

There wasn't supposed to be any argent in 71, they were supposed to be all black, but there are many documented cases of argent ones I believe.

I probably got the story a little mixed up, but Mark on GYC said during a quick trivia spot that the first ones made in 1970 were red. After being on cars, people complained about glare coming from the shiny painted surface so they switched to the argent for the rest of 70 models. 

A 440 base plate is 1/2" lower than a 383 base plate. The 383 base also has a single support in the front that replaces an intake pan bolt.

there are pre-production pics of SHAKERS in RED, YELLOW, BLUE & ORANGE body paint

IMO the ONLY body color that was used in production was RED - early '70 and not many of them
- 30 years ago there were very few - now just about every RED 'cuda has a RED SHAKER - was its original intent to be used on all RED 'cudas, randomly, V-code / R-code or in combination with ELASTOMERIC bumpers? 

the problem with multiple colors is inventory for the forecasted quantities expected - the SHAKER assemblies were pre-assembled at FRAM & shipped to the factories - every additional color added to the on-hand inventory required
----- at the start of the '70 model year 4 different assemblies would've been required on-hand: RED 440+6 / argent 440+6 / RED HEMI / argent HEMI (add colors, add engines, add Challenger = ADD INVENTORY)

debunk the "glare" theory - every RAMCHARGER DODGE (N96) Coronet R/T - Super Bee and a good percentage of Swinger 340 hoods came with 2 body colored hood scoops - "IF" there was a "glare" problem, these would've gone "organisol" or similar
debunk the "quality" paint job too much labor theory - see above hood scoops and add the Charger R/T & Coronet R/T door and quarter scoops made of the same material as a SHAKER bubble
      and some if not all of the above were painted at the same time as the body 

with the success of the 1970 E-bodies      eyes were opened and plans were expanded - COOL STUFF for everyone, the market took a beating, sales dwindled and OPTIONS got the axe 

this is my take on a scenario that may be close to the original intent of the '71 ARGENT VS. BLACK SHAKER bubble 50 years later, there is little or NO proof to support this theory ..........

'71 DODGE Challenger SHAKER ARGENT bubbles
                available on  340 & 383HP cars, ARGENT bubbles to match the ARGENT grills (2 set-ups for inventory)
'71 DODGE Challenger R/T SHAKER BLACK bubbles
                available on  340, 383HP, 440+6 & HEMI cars, BLACK bubbles to match the BLACK grills (4 set-ups for inventory)
'71 PLYMOUTH 'cuda SHAKER BLACK bubbles on cars w/painted grills: EV2, FC7, FE5, FJ6, GB5, GF7, GK6, GW3 & GY3
                available on  340, 383HP, 440+6 & HEMI cars, BLACK bubbles to compliment the body colored painted grills (4 set-ups for inventory)
'71 PLYMOUTH 'cuda SHAKER ARGENT bubbles on cars painted any color not listed above ^
                available on  340, 383HP, 440+6 & HEMI cars, ARGENT bubbles to compliment the ARGENT grills (4 set-ups for inventory)

that's 14 air cleaner assemblies needed on the line for whatever cars were being ordered & scheduled.  don't know when the plan was thrown out the window, but with E-body musclecar sales less than 1/3 of 1970's coupled with the rarity of the SHAKER hood - inventory control was probably a huge issue & cars got assembled with what was available on hand

I would say 3/4" is the difference, I have a 1970 440 base and a 383 base i my basement, both OEM.

Here are pictures of them.

@1971Y13

Could you give me an over all picture of what your measuring. 
Forgive my ignorance, I have yet to handle a shaker set up so I'm not terribly familiar with what I'm looking at there.
I know it's the pan but do not understand the orientation.
And thanks for the pics!

  He's showing the measurement from the flange of the baseplate that sits on the top of carb to the bridge where the nut tightens it to the carb threaded rod. This height measurement varies for each engine size/carb  on stock installation.

Just for you Cuda Hunter, why? Because your'e worth it!

While we're on the subject... This is on the inside of my bubble. Does it mean anything ?

Would it really be 14 different inventory setups?  More like 8 (4 engines x 2 finishes)
Assuming the engine callout emblems were installed after the shaker was pulled from inventory.

Regardless, your shaker finish theory makes aesthetic sense to me.
