7028268 Quadrajet Question
Is it possible for one of the number "8"s to look larger or different than the other "8" without this carb being a restamp? It doesn't look to have ever been tampered with but I'm sure anything's possible. Also, any ideas as to approximate value? Thanks.

Yes, the very early stampings are known to have different size letters, and many may have some of them stamped much deeper than others. We noticed this recently when we sold an early 1968 7028275 core. The first "7" was larger and deeper than the second one, and the "5" is also much larger and deeper stamped. After being questioned about it by the new owner, we went thru the core pile and noticed numerous other 1968 carburetors stamped in similiar fashion.
With all the restamps showing up on E-Rape, it makes folks pay closer attention to these things. Later years stampings are much more uniform and usually have the same letter height. It's still not uncommon for the first "7" to be stamped pretty deep, even into the early 70's......Cliff

Thanks Kyle and Cliff!!
Cliff, is what Kyle paid($110) representative of the value of this carb? I'm cleaning out some of my Pontiac stuff before heading to the TA Nats later this month and could bring it with me if someone had an interest in it. Jim |

It's difficult to evaluate the price of the core, a lot depends on the condition of the unit, and how much of it is still there? Around $100 for a 262 or 268 1969 core is a decent price, provided it's in good shape.
1967 268 and 262 cores bring more than later years, seems to be fewer of them around? The manual transmission non-RA carbs are moving up in value. All of the Ram Air stuff is out of sight, I don't know if you can even find any 273 carbs anymore?......Cliff

You can still find the "273" carbs out there. You will find them as re-stamps as shown in this e-Rape auction. Notice the plugged auto trans vacuum port on the front of the carb. The "273" carb, as far as I know, were never built with plugs. And I believe that the High Altitude valve on the rear of the carb should not be there as well. It looks like a pre-68 bowl to me. And the "3" looks very suspicious as well. All of this is JMO. I am not claiming to be a Quadrajet expert, but I would never have paid what the winning bidder paid for this carb. Word to the wise, be cafeful to not get ripped-off and study the pics before bidding. Do your homework. Know what you are bidding on before plunking down the cash. http://my.ebay.com/ws/eBayISAPI.dll?...e=STRK:ME:LNLK Doug |

Doug, the recent auction for the Ram Air 273 carb on E-Rape was an OBVIOUS restamp. The owner couldn't even provide an in focus pic of the numbers. I asked for a good photo, already knowing it was a FAKE, and they couldn't provide one. Just a word to the wise, for the 273 carbs....NO plant code and/or NO Julian date.....it's a FAKE, you don't need to know anything else about the carb!.....Cliff

When did Rochester start stamping the julian date on the base plate? Is the date on the body or on the base plate of a '68 7028273 carb? I've seen '68 carbs stamped both ways.

The date code stamped on the throttle body started for 1968 years production.
A few early 1969 carbs made late 1968 also show this style stamping or non at all. Remember that the #7028273 also were used for 1969 RAIII´s and may as well have the date code stamped at the same area as the rest of 1969 year production Q-jets close to the part-# and plant code. |

Jim, I thought I saw you at Norwalk, still running the 68 FB RAII?
I have a 7028273 carburetor in the shop, it has the date stamped on the throttle body, pretty sure it's somewhere around 1258 Julian date.....Cliff

Jim, running great as always. I love to watch your car run on those tires. I couldn't imagine trying to hook mine up on them, 9" slicks will barely hold it!......Cliff
