1 carb or two? If just one is there a possibility that it is too small & is going lean. Just speculating here but here's a BTT for ya

with the float level correct/fuel psi OK (confirm them) I would lean the jets so the cruise system at a vac level higher than PV tip in is in a good range then work on the secondaries/power systems. When you said accelerate is that part or WOT? (are you into the secondaries and or the power valve?). Carb might be too small/might not be enough psi/needle/seat might be too small. If your getting enough fuel to suppoert the accel then I'd jet down the primaries then work on the other subsystems. One at a time

65mph/68 jets/11.8-12.2: You could be on the main circuit which would make the 68 jets too rich.
Steadily accel = 13.8-14.2: If you are seeing this while the vacuum rating is lower than the pv rating, then maybe try a four door pv or try to modify the pvcr's.
Idle is 14.7-15.1: If you have achieved the highest vacuum level with this reading and it is a manual trans, then that should be good. If this is an auto, then that reading may be lean when you put it in D.
