Quadrajet identification.... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Cal69Chevy · 03-29-2002, 10:04 PM

I found this website that helped me identify my Qjet. The only problem is according to the numbers and legend this carb is for a manual transmission...which would be fine except I have an automatic. I was told by the original owner the carb is original. The trans is definitely original as it's on the options list in the glove box. Should I be concerned?

Here's the website if anyone should need to id their Qjet.

helps if you woulda posted what your number is, and what original tranny to truck was according to glovebox sticker

last digit of the carb number wil be even or odd,

even= auto
odd= manual

if the carb is a 69 carb then it wil be a 7029 carb if is correct, but you can never know if it is original

thanks to the website I know how to break down my number to determine what I have...that's the problem...the carb ID says it's for a manual trans and I have a TT400 trans.

7029207 last digit is odd so spec'd for manual transmission.

What can you not use a carb from a standard on a auto truck? I am going to convert to a 700R would be nice to know!

I believe the only difference as to automatic or manual, at least as far as carbs for our trucks, is the vacuum port on the back on the base. Manuals have it blocked off, auto's don't. Not sure, though, that's just what I've heard.
