Olds to Pontiac shaker conversion?
I'm sure it's been asked before but can an Olds shaker set up be converted to Fit on Pontiac motor. I keep looking for Pontiac shaker and all I see are the Olds ones and none seem to be in good shape. I have an Olds one in good shape, wondering if I could move the base ring on the shaker over to fit new motor. Any suggestions are welcome!
Happy New Year! |

You may be able to detach the adapter plate from the Olds scoop and move it over to fit the hole in the hood. The Olds air cleaner base is offset too, so you might have to do something about that too.
Also, an Olds engine is shorter than a Pontiac, so the Olds shaker adapter plate is about 3/4" taller than one for a Pontiac. There may be additional difference in the height of the air cleaner base too. So, when putting the Olds setup on a Pontiac engine, I believe the shaker would sit too high to fit under the hood. So, I think you'd have to do some height modification too. Also, the Pontiac q-jet has a fuel bowl vent pipe that is rather tall, so there's a hole for the pipe to be inserted into on the Pontiac air cleaner base. Olds base doesn't have the hole, so you'll have to make a hole in the Olds air cleaner base for that. Might have to watch for distributor clearance with the back of the air cleaner too.

the top fiberglass part is the same, but as you know the metal base is completely different. you could find a broken Pontiac scoop and remove the metal base and put your good top on it. that is about the only way I know of.

Someone here had a bunch of shakers for sale, the the "parts sale" section, it's been a while ago though...
There's too much of a difference to make an Old's unit work, (my opinion). Keep looking. I'm sure the Olds unit could be made to work. It would take a boat load of modifications. Keep looking...

What would be really nice is if someone would make a reproduction Pontiac shaker base so that all those mint-condition Olds 403 shakers could be converted to use on a Pontiac motor. Just drill out the rivets and reattach to the reproduction base.
Don't the L78 and W72 air cleaners use the same shaker/base? If so, couldn't the more common L78 parts could be used for the rest of the conversion? |

The shaker "base" you refer to is what I call the "adapter plate", since it adapts the same scoop so it can be used on several different engines. So, yes it would be nice if somebody reproduced the 400 adapter plate, and it could be swapped on to a 403 scoop.
Yes, the L78 and W72 400 engines use the same scoop and adapter plate. Of course the air cleaner bases for a L78 has the longer snout with a round end, and the W72 has the shorter, wider, oval snout. But the 400 shaker scoop and plate is the same for either one.
