This is a real deal 1969 Pontiac Ram Air carburetor. The part number is 7029270 XA. The date code is 0379 which decodes as the 37th day of 1969.
It was very hard to put a price on this carb since most that I have seen advertised are either service replacements or restamps.
I decided to put this one up on Ebay starting at $9.99 with NO RESERVE. If you are interested, here is a link to the auction:

Thanks for the ad,
Jason
