From: State of Confusion

I set the timing tonight. I thought it was okay when I checked it before, but I was checking from the wrong mark (the big notch in the balancer, not the line), and I hadn't removed the spout connector either. I found the right mark, pulled the spout, and discovered that the base timing was set to zero! No wonder it was struggling! I advanced it to around 12° and it seems a lot happier. It still has just a little bit of lag between putting my foot down and the engine revving. Maybe I'm just used to MAF sensor systems, and MAP rigs just respond a little slower? Whatever the case, it's running a hell of a lot better than it did before. I think I could actually drive it to town if I had to.

Now I just need to figure out why the tail lights, turn signals, and transfer case detent aren't working, fix the rear brakes, fix the rear wheel bearings, get an alignment, and figure out why the ABS light is on. At least now it runs! Thanks for the advice and encouragement. If you want to feel better about the condition of your trucks, I'm doing sort of a video log of this truck's resurrection (first one embedded below). The latest video should be up in the next couple days.
