I have new Accel high temp plug wires and header plugs. 4barrel Q.jet carb. I think this is all o.k. I am still leaning toward the cam being the problem. I have driven this truck for awhile
and this problem has just started.I also wonder if the lifters
may be part of the problem.This thing sounds just like when you turn your key off going down the road and turn it back on.
