7029204 Real or Re-Stamp?

[Greg L.]

I would like your opinions on this carb please.

Is it the real thing or an old re-stamp?


Oh and why are some carbs stamped as 7029204 and others as 29204?

Thanks,

Greg,

This is my grungy old original that was boiled out and re-dyed. Its a 205 from a 1970 454. They look very similar over all. However, the stamp fonts look completely different, for whatever that's worth.

Font SHOULD look different!

"However, the stamp fonts look completely different"

There were two different suppliers of QJets: Rochester and Carter. The dating/origin stamps were different (described in your copy of the Judging Guide) and they were wacked in different plants with different stamping dies.

The carb you show is Carter built QJet with conventional alpha-numeric date coding while the sequence the poster showed is from a Rochester built QJet with Julian date coding....

Re: Font SHOULD look different!

Jack, you may be right about it being a Carter licensed Quadrajet, but that EH doesn't look like a date code to me. If a date code, I would expect the second character to be a digit for the year, like E0, or May 1970.

Carter Quads seemed to be prevalent toward the end of the 70 MY. Mark Smith, a long-time supplier of dated carburetors to the hobby, once told me he had never seen a 70 Carter Quadrajet dated after May 70. I assume he knew what he was talking about; he had certainly been through enough barrels of Quadrajets. I was angling to get a Quadrajet dated at least June for my July 30 build car, but no dice...I had to settle for E0.

For those interested, Terry McManmon wrote an article for The Corvette Restorer summarizing observations of Carter Quadrajets during this period.

Re: Font SHOULD look different!

The EH is the broadcast code. Rochester built Q-jets had julian dates -- like both units shown. Carter built Q-jets used a letter number date code-- like E0.
I wish someone would tell us why some Q-jets had longer numbers stamped on them than some others.

Re: Font SHOULD look different!

Having seen several know restamps, if the right person restamps the carb you will never be able to tell it. Some have it to an art.

Re: Font SHOULD look different!

Thanks guys. Actually I think the difference in fonts on these two Rochester built units is due to one being a 69 and one being a 70. I have a few pics of 69 rochester units and the fonts look like the one that I posted. I also have one or two pics of 70 and later rochester units and those fonts look like the one from Tom's pic so I'd have to say that Rochester got a new set of stamps for 1970.

Anyone know why I didn't get a e-mail notification for any of your replies?
