440 and 833OD

If you go that route, I just gotta tell ya, buy some spares. I blew three of those up.
On two of them I put a lil too much torque into that tiny od gear and zing it was gone.(One was done with a 318)
On another my 367 tore off all the front teeth ; input and cluster zing I was walking. At least when the od gear went, I could still drive home.
With a BB do not pass in overdrive!

I have come across Mopar od boxes with two different od ratios and no gears interchange except the low. One set has an 18tooth od gear, and the other has a 20tooth. One might think the 20tooth would be stronger, and I suppose it might be; but my 367 sure couldn't tell. Zing, there goes another one.........
