Oh no the dreaded eldebrock performer carb sydrome, sounds like they loaded up the plugs if they are black, might as well toss them and buy another set dont try cleaning them its a awaste of time.
Question do you have a ignition box? I.E> MSD 6AL.
If you dont you need one, will help a bunch.
When you replace the plugs check the gaps make sure their not over .035 then when you get in running check ignition timing make sure the distibutor hasnt slip on you. With the trash in the fuel filter as you described you might have very well gotten some trash in the carb and got your needle and seat clogged so it wouldnt seat properly, also you could have some trash in the main jets which will make it run terrible too, either way you'll have to remove the tops off the carbs, no biggie and clean them as required. Keep us updated
Goodluck, Charles
