I agree with going to a double-roller timing chain, much better choice. I'm fond of the Cloyes double-roller with 9 keyway positions.
As far as the noise of a gear drive....it's not too noisey, yall are just too old!
I ain't dumb, I just ain't been showed a whole lot!

I ran an original Pet Jackson in a 1973 SBC. Whined, I was 18 and loved it, and never had a problem. As a PhD now I have no doubt they introduce unwanted and likely damaging harmonics. But I was using it with a solid lift cam which by nature will reduce these. I abused the shnokers out of it. Use a chain or belt.

I use Donovan gear drives on everything, I don't know why, I guess old habits are hard to break. Mine don't make any noise.

well that type has no floating gear set in it the jackson type has the idle gears banging around . were your s just has one . the belt is a much better way to go$$$$ but it is hard to beat to good chain set for the money
