Default Mystery Quadrajet - please help identify

Bought a carb at a swap meet some time ago - #7028282 (yes I am positive that is the correct number). Does anybody know what this thing is from? Looks almost exactly like a 1968 Chevy Quadrajet, but it has a later style Chevy throttle linkage. It is calibrated similarly to a late sixties Vette QJ - .065" jets, .035" metering rods, AX secondaries.

Want to try it out this summer. Found a float for it, but without an application it is kinda hard to find the specs. I was thinking of going 5/16" but that may not be right. The float has a shorter arm than usual.

As always,
Thanks!

I show that as a MARINE Qjet from a 1967 Daytona 427 CID.

If the vent tubes are cut at an angle, it's a marine carb. Ran a spare one on my 1 ton truck for years. No problem.
