how are the 833 overdrives???

I have one behind the 360 in my 68 Barracuda with 3.55 gears. I have no issues at all with it at all. The 360 pulls the wide gear spacing with no problem (I have run a best of 13.7 @ 102 with a very traction limited 2.2 60').

It may not be the best choice for a drag car but for street driving it's a good choice. I get 17-18 mpg around town and 21-22 on the hiway. I am turning just a tick over 2000 rpm at 70 mph.
