Thank you RON

Welcome, Ron. Don't be sorry to ask questions here!

I also have a '69 Firebird 400, and can help you out with numbers. The intake manifold is 9794234.

Vikki,thank you.I saw one with the #9790418. What year would that be off of? I have or know the numbers for everything, but manifolds( I would like to learn). I have been into GTO's For 20+ years, firebirds are still pretty new to me.

9790418 comes up as a '68 2 bbl 350 or 400 Firebird/ big car. Your Firebird 400 should have a 4 bbl Quadrajet.

Take everything with a grain of salt and try to verify with another source.

Vikki,Again thank you so much.

You're welcome!
