It would be almost the same as putting a 17-tooth counter sprocket (stock is 16 I think) on your original 36 tooth wheel.
It would cut down some of the "buzz" you get on a 350 by reducing rpm at a given speed.
If your engine has the guts, you could go faster as well.
This is something a lot of 450 guys do, just for comfort.
So, your decision.
You can change rear sprockets, leave it as is, whatever......
incidentally, I remember the Sprockets dancing well - good stuff.
