Passon Performance 5-speed

The A833od has pretty wide splits allrightee, but if you have an automatic-type cam of 112LSA or more, it ain't all that bad. No; not hi-performance, but a few more cubes makes all the difference.
3.09-1.67-1.00-.73od and splits of .54-60-.73 Wait aren't those same splits found in the 727? Well not quite;
2.45-1.45-1.00 and splits of .59-.69 .. But the A999s have ratios of
2.74-1.54-1.00 and splits of .56-.65, and everybody loves the A999
First to third in the regular A833 is 1.4/2.66= .526 so poster jos51700 in post 202 is pretty close; .526 ain't that far away from .540
The difference is with the regular box you would probably run 3.55s ,so second gear would be 3.55x1.92=6.816, whereas with the OD box, to get a 6.816 second gear, you would run a 6.816/1.67~4.10. Then your first would be 12.67......... and you would hardly notice the wicked split. Well OK I hardly noticed it with my small-cam 367, around town and such.
Here are your road gears with the 2.66 box and 3.55s, your typical streeter combo
9.440-6.82-4.97-3.55.. and with the ODbox you might run 4.10s, for roadgears of
12.67-6.85-3.91-2.99.. So in the OD box,low is a bit low, and direct is a bit out there, but for a streeter, that 6.85 second gear will get you 60 mph@5100, and that 12.67 is a wicked launch, and that 2.99 is super nice cruiser. So that just leaves the direct gear as ugly, but you will likely wind second out to 6200/73 mph,so you won't get to direct for awhile.
That ODbox ain't all the crap some people (not alluding to anyone specific; jos) make it out to be; at least it doesn't have to be.. But yeah if you run it with 3.23s or 3.55s, and a pipey-cammed small-engine,you need to give your head a shake.
And the truth is, you can run that box with any rear gear you want, up to ~4.88s, to get the same equivalent 3.55 hiway cruiser. But after 4.30 first gear becomes crazy-low;waaay too low for a street 360.
I ran it with 4.30s and hit 60@ ~5400 with a ~5200 peaking 110LSA, two-degree-retarded cam, in my 367; Shazaam!!
And yes, that box was terrible with the 292/508 cam and 3.55s, even with the cam advanced to 100 and at 11.3Scr. And to think I traded a mint 2.47 close ratio box straight up for it! Sheesh I was desperate.
