Hi All I’m at my wits end fighting this. I have a 428 engine in my 1969 Firebird.
The car starts and runs well but for some reason I get a loud high pitched squeal starting around 3k RPM but runs well. It sounds just like a belt squeal but isn’t. I’ve removed the belt from the alternator and still get the squeal. I then removed the belt from the Power steering pump and still have the squeal.
I’ve replaced the water pump already and also the alternator and both belts. No joy. Same thing
