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.

ok, ill check. i already had to pull the drive shaft, since i took out my tansfer case. also, my front drive shaft is not hooked up, it hasent been since i got it. so could that cause it to shake? since i cant drive it right now, ive been working on the inside, all i have left to do is install a new bright switch. so now im bored and cant start on the body rlly, until i can drive the truck to my buddys shop.
