Right Carb for Motor?

[MM6200]

Hey Cliff
 Back to the Quadrajet scene since the 1970's.

Just got a retirement project and am doing some research.

I bought a 1967 GTO 400 325HP with matching 400 turbo for the project.
When I picked up the motor, the young man gave me several parts in a crate.
There was a Quadrajet in the crate. Part number 17057253.
Used your handy dandy decoder and found out the carb to be a 1977 Oldsmobile 350.
Used your handy dandy forum search and found out this was used on automatics even though it is an odd numbered carb.
Read your handy dandy Tech Talk to find out the later 1970's carb were desirable to the 1960s. I really don't know why?

The Pontiac motor will be rebuilt to factory specs as much as possible.

Is this a good Quadrajet for the Pontiac motor since the Olds CID was different along with emission standards?

While I got you, I plan on ordering one of your HR kits. What jets and other options you discuss do you recommend?

Thanks a bunch.
Mike

 Welcome to CHP!

 The correct carb for your application would have been, #7027262 w/o A.I.R or #7037262 w/ A.I.R.

Thanks for the reply.

The car will not be numbers correct. Putting this 67 GTO motor in 65 Tempest. Keeping the bench seat and column shift. Will have a 326 2BBl and 2 speed Tempest-Torque for sale soon. Runs good.

So will the Olds carb work on the Pontiac?
Pontiac motor has 2:11 intake valves. Will also have headers on it.
If this carb will work, are there emission ports I will not need on this carb?
And can you recommend jets and other changes to match the carb performance to the motor?

 I think the carb you have now would work for your application. Cliff will know.

The later Olds carb will work fine for what you are doing.  They are excellent units, and superior to the original 67 Pontiac carburetors in every area.

It will need an E-choke conversion, and some tuning help being emission calibrated.  We can help with parts and advice on how to set it up exactly for what you are doing.....Cliff
