I see that my thread has been "modded."
The gas tank was totally clean inside - not one spec of rust and no sludge/gunk. I was amazed. It did have some small rust pinholes though that came through from the outside and that has been patched.
Thanks 79coyotefrg, I'll address your questions here:
Block decking: Don't know exactly, but not very much. Enough to make it flat. Not more than .010"
I'm in Seattle, so sea-level.
I've been working slowly on the carb, one thing at a time which means the idle jet first. It's a 70 now and the mixture screw is now at 1-3/4 turns out for best idle. Part throttle pinging is pretty much gone but every once in a while I still hear a trace of it. Engine doesn't feel like it has the power it should, have to floor it to really get it to go so will start richening up the main & secondaries and see what happens.
Timing is still at 10* which judging from what LCE told me should be fine (24 total without vacuum). Could use a little more total but will deal with that later.
Exhaust manifold is the original from the 22R, the 4-into-2 setup that has two separate pipes that run underneath the truck and join before the cat. Looks like it should flow decently but definitely not as well as a header which will have to wait a little while. The money gun is smoking hot and needs a rest after ordering suspension today and also replacing the power steering pump and pressure hose. Work is kind of on-and-off for me as my company is between big jobs right now. Should be plenty of hours coming in a month and if there's overtime that = header.
I have a 20R distributor but it has the dual vacuum ports. I'll get around to playing with it soon.
Thanks for all the input. Should I start a project thread for this truck? I have quite a few pics of the engine assembly and other stuff here:
