Let's see an 87 V-6 no balance shaft with a crankshaft that wasn't the
best design for smooth running. And it idles a bit rough.
YUP sounds 100% normal to me. Think of the way that engine runs. The
power pulses are not evenly spaced. Kind of like if you built a set of
stairs, with every third step 15" tall. Think it might affect the way
you run up them?
Oh and did I read that you have a MSD ignition on this truck? That isn't
going to do much on a stock engine.
