surveyor, the marks are sometimes hard to see. I have a white line painted over the 10 degree mark. There is also no vacuum advance - the computer controls all advance. The spout connector jumps those wires, otherwise the truck would be lazy from no advance and the computer would store a code. If you can find the marks, rev the engine with the SPOUT connected, and you'll see the timing jump advanced.
