Sounds like a fucked bearing mate or something rubbing. But if it was something rubbing you'd expect a noise even when you're not revving it, the fact it gets louder as you rev it indicates a knacked bearing, I'd be looking at the alternator as well

common thing on old 8vs the bearing on the alternator, get some white grease on it and it should quieten it down a bit
