The $20 mystery Q-Jet (back to looking at it again)

[pagrunt]

After failing at bending the POS Pypes tail pipe I went to the Q-Jet I got last weekend. The known factors are it's a '85 (March '85 based on main body casted date code) for a truck with an auto. It has signs of a past rebuild (has a epoxy in plug at the fuel/filter inlet, clear sealer on the electric choke.) Looks like it had a clean storage, no grime. The big unkown is the specific ID code since someone grinded it off. I would like to atleast reseal it but with an unknown history a rebuild would be the best course. I'm just trying to figure out which kit to get. It's bad enough I still have the Holley 4175 (what was on the old engine) to rebuild & now I have a Q-Jet to do. Atleast I'll have options on which to use when I get them done. But any ideas on what other ID marks there might be to look for?

Post a few pictures. Sides, bottom, top, down the primaries...

I have no idea why someone would grind off the code. But since it is I would just use that quadrajet for parts.

I bought a reman Q-jet from Summit when I ditched the CCC carb on the Monte. They apparently are some of the offenders who grind off the numbers. The carb currently resides on my 80 K10. When I needed some pieces for it I ordered from Qjet.com, you can match up what you have there. When I was a kid working at an auto parts store no number = no rebuild kit for you.

I did get the one thing stamped on the top passenger front that I forgot about.

It could be a Frankencarb made from all sorts of parts. I'd open it and see what gives. It may have some pretty good jetting since it was on a truck. At least it does not have the idle enrichment solenoid many '80's trucks used. It otherwise looks like a decent carb.Some online carb parts places show the air horn gasket for comparison so you can match yours up.

Here's the primaries

That IS odd looking.

It has been years since I had a Q-Jet since I have been using the Holley since 2000. If it is odd I'll have to go with I'm told. I can't remember that far back.

The primaries look restrictive or maybe it's the angle. Look at this one. I only found some that have the extra screws on the front of the air horn when I searched '85-'90. This one has a number you can probably use to find a kit. https://www.ebay.com/itm/1985-1991-...428764?hash=item238b730e9c:g:VJsAAOSwIQdZFeqY
