Alu OD 833

The 3.09 is sorta the best part of that swap, but it sure makes for a looooong 1-2 split. The 3.09 lets you run 16% less gear in the back for the same take-off power. But if you do that , then you lose ~25% on the shift into second. Here's how the ratios compare;
2.66-1.92-1.40-1.00std box, versus 3.09-1.67-100-.73od.
If you were using 3.73s with the 2.66box then your final drives would be pretty sweet ratios of;
9.92-7.16-5.22-3.73with the standard box
To get the same starter gear with the od box would require ~3.23s. Your new final drives would be;
9.98-5.39-3.23-2.36 with the od box.
Now compare the second gears; 5.39/7.16 =.753 or a loss of TM in the amount of 1-.753= .247 or ~25%. with the od box. So a better idea might be to make second gears the same, ie 7.16. That would require a rear gear of 4.30s. And you get
13.29-7.18-4.30-3.14with the od box. Of course now you have a drag-race starter gear. And third gear is way out there again..Since nothing works really all that well, you can split it up the middle, running 3.73s again. The new final drives would be;
11.53-6.23-3.73-2.72with the od box. This is a reasonable compromise, if your engine likes to cruise at 65=2200
So IMO, this is a very wide ratio trans, but suitable to be used with an engine designed to work with it. That generally means a hi-torque lo-rpm engine.... like stock 318s and slantys.
A 360 will pull it just fine with a small cam. Or at least one with an early closing intake valve to trap the pressure.
There is a guy here on FABO running one with a 340. I forget what cam,maybe a 268, but he says he's happy.
I can tell you for sure it sucked with a 292/108 cam in my 360 @11.3 Scr.
I can tell you for sure that with a 270/276/110 Hughes and now at 10.9Scr, it was sorta bearable. But I bought the GVOD PDQ, to start splitting gears cuz the splits in the od-box were just too far apart at high-rpm, for my combo. That gave me 8 usable ratios. But having to split ratios in traffic proved to be the death-knell for that combo. I was done with it.
I swapped that box out for a 3.09 early Commando box, plus the GVOD still; 3.09-1.92-1.40-1.09-.78od; splits of .62-.73-.78-.72od : prettysweet. That combo has been in there now since 2004.

For OP in a DD, the 3.09odbox will work just fine.
