update: couldn't even use the timing light on it because it wouldn't run for long enough. I am about 99% positive the chain is timed right.
Pulled the oil pump out again and moved a couple teeth on the gear (dizzy shaft). Got the truck where it will run and rev up. Runs a little rough. Checked with the timng light; #1 fires 180 degrees off. The #4 fires at the correct timing the #1 should be at.
What does that mean?
