Really bogging down in 3rd gear

Do we know what were working on yet? I mean, Im guessing its an early A(pre 67) with a 3 spd manual trans, a Carter carb and points, with likely, 2.76s, or so, out back. Sound close?
- IIRC, Carters have metering rods with their attendant springs.
-The lobes on the point cam do not have to be sharp.Its highly unlikely the lobes are significantly worn. I have seen many high mileage engines with well functioning point cam lobes.And, yes that part can be replaced.Bear in mind that the point on the cam is not a functional part of the system. the points open well before that part comes around to the rubbing block, and close well after. That point could have been manufactured well rounded and not affect the operation of the points. The status of the rubbing block is of far more significance. But, as long as a proper point gap is achievable, and more importantly, a proper dwell measurement,then all is well. Once the dwell falls too low, the coil saturation suffers and so does the ignition performance, under load.
