1972 Corvette Carburetor

[thumper]

Hi everybody!

My friend is working on a 1972 Corvette with a 4 speed manual transmission, 350 SB.

The carburetor # is 704 2902, which I believe is for an automatic transmission.

On the drivers side is an electric solenoid which appears to position the throttle.

What is the difference between applications for manual and automatic transmission carburetors, and can this

704 2902 be corrected to work properly for an automatic transmission?

Thanks for any help, Thumper

Wow, I have the same question.  My Q-Jet casting ends in an odd number, raising a question about a manual transmission application.  (My car is an automatic.)  What did your friend find out about this?

 This is a common misconception. A lot of Quadrajet stampings end in a odd number, but yet, came with a A/T. And vice-versa for M/T. Why Rochester did this, who knows.

Thanks, I'm seeing that.  Good news, good news.  But what do you make of that last character?

For the most part auto carbs will end in even numbers, and manual transmission carbs in odd numbers, but there are several exceptions to this basic rule.  Quite a few of the exceptions are with Oldsmobile carburetors, and some Service Replacement numbers......Cliff

That would account for mine, then - it's for an Oldsmobile, and I also think it was a service replacement part.
