Anyone know what size cfm the stock Quadrajet is on a 1983 Z28 (LG4)?
Thanks, Tequila

Sorry, I forgot to ask if this carb is computer controlled?
Thanks, Tequila
It is computer controlled if it's original. The old ones were 780CFM, not sure what they were by '83.
This doesn't answer questions, but the site has gobs of data/codes for just the 1983. Hope you enjoy. S
Quadrajets ranged between 780 and 830 cfm depending on the application. Which ever version you have, it's plenty of carburation for any small block.
