i have not yet picked up a spark plug tester but i do know that the
wires and distributor cap and rotor have all been changed resently but
i will check to make sure there hasnt been any damage done in the
installation process.

after a visual inspection i did not see any vacuum leaks, the tapping
im just going to adjust the lifters, i would have to say less than
130000 miles on the motor we dropped a new motor in that had only
about 50000 on it

I'd check compression first. Did the problem happen slowly or suddenly?

I doubt it could cause that severe a problem, but disconnect it and see
what happens. If the engine runs much better with the sensor disconnected,
the sensor is a problem.

But I don't think the sensor is the issue, it's more likely to be
timing or air. It's easy enough to rule out, though.

Does the oil smell like fuel?
AAP diaphragm in carb is common fault...

ok what i have done so far is installed a new O2 sensor and seems to
run a little better but still rough idk if the computer needs to
relearn or what. As far as the hard start i am in the process of
testing the voltage from the ignition coil but i must ask do i need to
have KOEO and have the black lead on ground and positive where the
ignition coil wire comes out? I have the specs on how much it should
read also where is the connector or wires i need to test for the
primary side? Also do you no the specs for rocker arm adjustment? i
looked in a hanes manual and i think it is .0008-.0024 (intake) and .
0012-.0028(exhaust) i just need some clarification. Once i am able to
get rid of the rocker arm play i can listen and do some more tests.
