What gear ratio did you usually use behind the OD?I have modified cars to run the 833 OD all the time out of maybe 25 conversions only 1 person didn't like it !
I have raced them behind 440s as well , nothing wrong with them at all .
Most were installed behind 318/225 engines so almost everyone I have bought from a wrecker has been in good shape too .
With the Dana 3.54:1 rear my A833 4-speed is at 140 MPH approaching 6k RPM. (28" tall tire. 15" rim) Thats about as fast as I dare on a near stock B-body. (Although the car is remarkably stable. Floating nice.) The 440 is still pulling a bit. But definitely getting to valve float area.) So with these O.Ds? How fast do you need to go? 140 MPH on a street car is criminal?
Yes, I've got the Passon OD gearset in my A833, and the ratios are great overall. Running 28" tire with 4:10s. Tach runs around 2900 at freeway speeds, 3:54s would probably be better for freeway trips.Anyone ever run one of these? If so, do you have any comments?

Agree, and you must have the shifter linkage adjustments dead on for easiest shifting. In mine, reverse can be difficult to engage at times, requires more effort, and is noisier than stock A833 gears.Now running the Passon OD A833, around town never go beyond 3rd gear, but on the freeway into 4th gear(0.8 OD). RPMs dropped about 20% running to about 2650 @ 65MPH. 1st gear is almost same as these standard A833 (2.66), 2nd gear (1.59) is higher vs. (1.93), 3rd gear is (1.0) ratios are very close to those for a 3-speed torqueflite. Overall very pleased with the OD A833 transmission, only other comment is when shifting U can feel the bigger gears so a little more effort is required. Passon was very supportive, only negative it takes a couple of months to get it built and shipped.
Just my $0.02...
My understanding is the Passon Helical gear angles are different than stock, and more noisy as a result. Running 80w-90 gear oil helped quiet them down for me. Yes, the ratios are perfect, and a lot of fun with 4:10s.zzß"noisier than stock A833 gears"
I've been running one for a few years now and this is the ONLY complaint I have. All gears that work through the countershaft (not just reverse) are noisier than the 18 spline I replaced with it (don't have near the mileage on it either though (still breaking in?), were 18 splines loud when new?), but the gear ratios are perfect.
