Alright, I am getting so frustrated with this thing. I have put new plugs, wires, distributor(HEI). Rebuilt the quadrajet per Cliffs book. Replaced vacuum hoses, and the fuel pump. When I put the hei in I took out the inline resister to get a good 12 volts to the distributor.(sorry 71cheyennesuperlongb)

When I drive this truck, it will have multiple small misses. You can feel it not running smoothly in the pedal and in the seat. Seems to be worse at lower to mid rpm ranges. At higher rpms it seem to smooth out.
I appreciate any and all suggestions you might have. Thanks
By the way it’s my 69 GMC K10.
