someone school me on my A833 for my swap Please

Thanks DaveBonds!
I was just reading on allpar and it is infact an overdrive with the 1.00 for 3rd and .73 for 4th. I will look into what I can fond for a decent priced bell housing, but I did find the brewers has one for the 75-80 A/F Body smallblock which also works in the trucks also.
