The "bog on the top of 4th gear" sounds like it may be running out of fuel to me. I hear the that Q-jet has a relatively small bowl for the CFM it can flow, you may be running it dry.

I'd look into recurving the ignition for faster advance if your distributor is in fact in charge of the advance curve (not the ECM). I agree with you that your numbers sound a little slower than I'd expect.

The G-techs are usually a little optimistic if anything from my experience, by a couple tenths.

If he's got a CCC carb the ECM should be controlling timing. Adding a little base timing might help.
