deanlemans81,

That blue Grand Am looks like the one from Hot Rod Magazine that I made mention of earlier in this post 🙂 .

I have no idea where it came from, just came across it on day while googling lemans pictures.

Hey 85-ss good info and links, you saved me from digging through boxes of car mags 🙂

Love the shakers! But when did Pontiac use Chevy Rally wheels?

 

[supkylesup]

The early style rounded shaker was used through '76. Early '77 used a low profile more squared off shaker with a pronounced ridge down the middle. Mid-77 through 81 used the same style shaker with a higher profile and more of a rounded ridge on the top.

70-76 shakers all had the larger single opening. In the pic above they are as follows:
-(left) rare early 77 shaker - lower profile with more pronounced ridge (non-functional)
-(middle) late 77-81 shaker (non-functional)
-(right) 70-76 shaker (only 70-72 were factory functional, 73-76 had a riveted/screwed on cover that could manually be removed)

Unlike most other air induction setups of the time, I don't believe shakers ever used a vacuum operated switch - I think they were all solenoid activated.

As mentioned, every engine option had a different shaker (difference was mostly in the base) to centre it properly and have it sit at the right angle/position. I am not sure what my shaker was originally from as I bought it without the metal base but I believe it was from a 400. I found a 305 base online (has a smaller diameter breather ring that I could use with my factory SS assembly) and mounting it involved an 1/2" offset and location/angle modifications to properly align the motor in the Monte engine bay and match the hood angle. I also have a low profile '77 shaker as well as another "tall" 403 shaker as spares should mine ever get damaged.

Here's some links with lots of good information for anyone interested (including the HPP article Dean mentioned):

Great info but you wouldn't happen to have any links as to where to possibly buy one would you?

The Pontiac Beaumont that was mentioned above - a Canadian only model based on the Chevelle:

...as for where to buy a shaker - local automotive flea markets, ebay or Pontiac message boards would be your best bet. I bought some of my shaker parts from Howard Tucker who runs the www.pontiacplus.com website.

Beaumont wasn't technically a Pontiac but a separate line sold at Canadian Pontiac dealers. At any rate, I wasn't thinking Canada, since they had Chevy engines and the frames for full size were also Chevy, they just looked like Pontiacs. The full size that is, the Beaumont looked like a b*st*rd step child. However, '68 Yenko Camaro used Pontiac Rally wheels with Yenko centers. :wink:

I tried to copy the 3 articles linked above, for future reference but they came up garbled. How can I copy them?

Rear spoilers fall under the same category - completely useless at street car speeds...

But they look good! 8)

Im still yet to find a monte carlo with the reversed style shaker hood that was on the challengers.
