36 BB Vanguard squealing sound when cold

Hey guys, have a 36 big block vanguard, only has a few hrs on it. Its makes a considerable squealing sound when its cold, after a couple minutes, when reached normal operating temp, its gone until the next cold start.

Kind of sounds like a belt squealing, I think its coming from the pulley clutch area, not saying its that though I don't know what it is.

Was wondering if anyone else with the same motor has had this before or maybe its a normal characteristic of this motor?

Hey Greenology, I did notice that noise on mine last time I started it. I was thinking hydro belt too, but mine's not a squeal, more a high pitched hum. It goes away when you increase the revs.
Will try and get a better listen to it in the morning.

Oh right, so might be a characteristic of this engine Yea I was actually going to call it a hum! haha. But the high pitched part confused me haha
