I have seen multiple references for a '69 GTX 440 4 speed 4.10 car that trapped 104, with a 13.7ish ET. It's been referenced in various coffee table type books, but I can't remember where I read it.

This one had a 69 X with a 727 and 4.10s turning 13.7 @ 102.8, and a Charger 500 with a 727 and 3.55s turning 13.9 @ 101.4. That's a great website if you like reading through old road tests by the way!

It seems to me that most 440 B bodies with 3.23s and a torqueflite would trap 97-100 MPH, but that trap speed started gaining with more gear. I've seen tests with lower trap speeds, but honestly there doesn't seem to be that many. 98 MPH for a 440 4 barrel with 3.23s seems to be about par for the course.

I think the 6 pack setup is worth 2 MPH vs the stock intake and 4 barrel. It seems a good running 4 barrel car with 4.10s would trap 102-104, and a good running A12 car would trap 104-106. There are also plenty of tests from 70/71 B bodies with the 6 pack and a 727/3.23 combo and those seem to trap 99-101 MPH.

A friend bought a loaded '67 GTX convertible, 4 speed, brand new. He recalls running 14.60s-14.80s when it was stock, which he thought was pretty strong for a heavy convertible as it wasn't much off what hardtops were running.
