Re: squealing noise going with the revs after build
Check to make sure your belt is tensioned. My '84 T/A has V belts, and you have the serpentine (I assume) but mine was squealing with the RPM's too. I though I'd tensioned the alternator belt properly but hadn't.

Re: squealing noise going with the revs after build
When ever i have had this problem it's been a loose belt or the PVC system wasn't vented properly (didn't have a intake filter installed). But the PVC problem was more cadent and less of a screeching squeal like the belt. Mine was a loose power steering belt.

Re: squealing noise going with the revs after build
