It does NOT sound like the crankshaft is hitting anything and does not sound fast enough to be related to the cam (it turns half the speed of the cranks).

Distributor not seated
Starter dragging or rubbing the flywheel
Timing chain rubbing the cover
Oil pump shelling out
Accessory (AC Pump, Alternator, PS pump) dragging/rubbing/hitting/dry
Transmission pump dry (Is there fluid in the transmission?)
Parking Pawl dragging inside the transmission
Transmission in gear due to improper adjustment....
Too long of a bolt in the TC cover dragging on the teeth of the TC


Just spitballing to throw out ideas.......

I didn't remove the oil pump but did remove, clean and reinstall the oil pump screen. I guess we will find out if something fell apart after I pull the pan tonight.

I have a little over 4 quarts of ATF in right now as I read you should not put all 10 quarts of ATF in, but start with around 4qt, shift through the gears, and then put the rest of the 6qt in. I hope this is correct.
