The p0300 is a random misfire. Try to clear it with new plugs and air filter.

clean the distributor (i'm not sure which ignition system u have). try replacing the thermostat to see if it stops the rich mixture. engine running too coool?

its a vortec 4.3. Would bet money the Fuel pressure regulator on the spider injector is leaking and dumping fuel into the intake. Is it hard to start after only leaving it for 30 min to an hour? A fuel pressure test and leakdown would pin point a fuel problem. Or pull the upper intake and look for clean spots, it should be dirty. Oil will smell like gas if it's leaking

I would check timing make sure your on top dead center pull the cap and your rotor should line up with the mark on the base of distributor it is 6

1860 valve body needs to be update some reaming needs to be done on a certain passage way
