Hey all,
Got a whistling/ whirring noise from the front somewhere. only happens in gear and with the throttle on (under load). It speeds up with rpm.

Can't seem to find it. Have no vaccuum leaks at hoses or brake booster, no belts squealing. disconnected mechanical speedo thinking that was it, it wasn't.
its got a brand new TCI trans and stall.
Could my alternator or power steering be making the noise or do I have a carb/ intake leak that could make that kind of whir/ whistle?
Thanks in advance.
