a friend just picked up a bone stock 5.0.
the motor screeches on the startup, and does NOT sound like a belt screech. :no
We changed the oil w/ lucas stabilizer filled up with the good gas and still no luck.
It only makes the noise on startup, we noticed a cloud of white smoke when we punched it last time. We tried it again with no luck. So it looks like its selective on when it throws out that puff.

Any ideas? Motor has about 120,000 on the clock.

Completely white is coolant, but if it has a blue screen to it, then it's oil. Pull the belt off and start it up. Could be pulley bearings going bad as well. Also tob could be on it's way out slowly.

Pulley, slipping belt or balancer
