Quadrajet prices
Just wondering why later quadrajets are worth more than earlier ones? For example, I have a 78 one on my 74. If I wanted to put a new 74 one on, it's about 50 bucks cheaper. There's probably an obvious explanation, but I thought I'd ask.

Different year Quadrajets have different choke setups. Some have divorced chokes, hot air chokes, electric chokes, etc. There are also differences in emissions controls, jetting, etc., that can make a difference in resale pricing. Late Quadrajets also were computer controlled, which complicates them.
Generally, each year and specific model is somewhat different and costs different. When you ask for a Quadrajet (like most other parts), add the word "Corvette" to the name of the part and the price goes up considerably it seems.
Even if you have a different model Quadrajet, a good carb guy can set it up for any specific car to run at its peak, regardless of whatever car it originally was instaled on.

lets see, 1300$ for a correctly numbered original carb that has been gone over, boiled out, rebuilt, new bushings, and jetted correctly (per factory specs) for the application.. or 200$ for the same thing with or without a restamp. hmmm.. only if you want to pay 1300$ for a number vs. 200 for the same thing without..
just depends on what you are looking for.

I have a 7029207 dated 2958 in my stash of goodies. I don't know if this is a '68 or '78 manufacture, as I know is this carb number was a service replacement for quite a while. How can a guy tell for sure?

Q-jets manufactured after a certain year (76?) had an ID number that began with "1".

That would be a Chevrolet Quadrajet for a 1969 with manual transmission, manufactured on the 295th day of 1968...

I'd be careful jumping to conclusions- a 7029207 2958 could be a Julian date 295 (October) over the counter 1978 service replacement, which are very, very common and much more plentiful than 1969 QJets.
NCRS judging guide does list a code "DA" for the 1969 #207 350 HP carb.
You are looking for a 7028219, code DG. Be sure the julian date is earlier than your build date.

Thanks for the decode link!
So my Q-jet from my 68, which by all other numbers is original everything, turns out to be made in 69! Another engine I picked up has a 68 date. One has a plant code of IF, and the other DH. I have to wonder if the carb on my original engine has been swapped by the first owner.

A regular Julian date calendar would also show both days at Oct 1.
