Default Carb Identification?

I bought this carb 6 years ago when I found that my original had a leaky fuel inlet. I was told that the original carb was unfixable so I bought this newer one.

After having it on my car for a month and putting less than 10 miles on it, I was told my old carb was easily fixable with a helicoil. So I took off the new carb, emptied it of gas and out it in a box.

I just remembered I had it. I know at the time when I purchased it on Ebay I paid 270$ and it was correct for a 427 manual car. There isnt a point for me to keep it any longer and was wondering if anyone could help me identity it, It appears to be in new shape and there is no stamp on the the location that normally would be where you ID it.

I have more pictures available if I need some other angles,

thanks
jim

Looking for that would have been my first suggestion. I don't know enough about carbs to identify this one, and the fact that it looks pretty similar to mine won't help very much.

Can you look up the old ebay listing from where you got the carb? Maybe the seller gave the carb number

I checked, Ebay doesnt go back far enough. I know it was a replacement carb for 7029215. The carb for my engine and transmission.

You might want to ask Lars about a Q-jet without a stamp.

That carb appears to be a commercial rebuild. The dead giveaway is the shiny plating on the accelerator arm, throttle linkage, air flaps, etc.

Commercial rebuilds are often a mixed bag of parts - a fuel bowl from here, an air horn from there - so it's often impossible to really "identify" one.

That carb is a commercially rebuilt carb, which will often have the ID numbers removed so you can't tell that it's been pieced together with mismatched parts from various years and makes of carbs. You're very lucky that you were able to get it running at all - most commercial have significant serious problems.

The 7029215 is the same as mine on my 69 427 4 spd. It has a bit different base on it to work on the stock smiley manifold and if you use the one shown in the pic, I think you will find that there is going to be a vacuum leak at the front of the carb where the heat bypass is (the smile) in the intake. The later carb bases don't extend as far forward to completely cover the opening but just come to the edge of it creating a big leak. The carb you show looks like one from I-5 on ebay that is made up of mismatched parts. They grind the numbers off. I bet if you look at the vacuum tube on the pass side that comes through the divorced choke, you will find that it is just a hole drilled in the side of the carb with a tube stuck in it as there is probably not even a casting provision on the body for the tube.

xp -
If you post a photo of the other side of the carb, I can tell you what the carb is made to appear to be. As noted by CanadaGrant, the carb is a mix-match of parts: The throttle plate has the big-block type throttle lever used in '69, but the air horn (the "top" of the carb) is a post-69 without the vent "doghouse" and with the doghouse vent provision not drilled in the casting, so that part of the carb is likely an early '70s. I'd suggest hanging it on your garage wall as an ornament...
