I think you have a couple problems. 1. A tuning issue and 2. bad tires, wheels, or U-joints. Its sometimes hard to tell if a U joint is bad without pulling the driveshaft. I had a u-joint go bad in my old 78 suburban and no matter what I did i couldn't get any slop in the driveshaft indicating a bad u-joint. Once I pulled the shaft (to replace the carrier bearing which I thought was the problem) It became very obvious that the middle u-joint was trash.

As for the delay in acceleration i think the timing is off or the accelerator pump in the carb is not working.
