Just spent about 900 miles driving this guy, half of which was done with about 17* of timing advance. I noticed a little loss on the low end, but she rips a little harder from 1800-2200.
When removing the #1 delivery valve, we found a broken spacer washer thingy underneath it. Reinstalled for the trip home (ran the same) but hoping that may contribute to some of the #1 weirdness it's had for a while.
Also got all new fuel and brake lines Saturday at Chad's house.

This will totally jinx it all, but it is running as well as it has since I have owned it right now. Governer springs would improve drivability some. Beyond that, I see delivery valves and injectors and not much else.
