Need help Identifying this carb

I don't remember whether this carb was in the trunk of the 1970 442 or the 1969 Cutlass. But I think it is from one of the two. The number on the side is 7043256 RH

I think that number is for a '73 455 (the 4th number is the year).

It's from a 1973 Olds, so it's not from either of those two.

The 73 carb is a nice unit to use. They did a lot of idle circuit clean up for the EGR and emmisions.

would you care to expand on that statement?
also, the egr is inactive at idle.

I had one built by a guy who has been building Q-jets since 1965. He told be that the 73 up carbs had better idle circuits because they had to run cleaner @ idle for emmisions. I understood him to say it was the EGR had something to do with it. I had one on a street 87 G-Body 350 CI Olds and it ran clean,sweet and fine.
