Dirtball,
You might also check with B & M. In the 1960s they built those transmissions called the B & M Hydrostick in versions varying from performance street driving to drag racing behind supercharged Chevy, Olds and Chrysler engines. They were widely used for a long time and there might still be a B & M old timer around who can help you.
Here's a story about the Stone, Woods & Cook Gasser, a '41 Willys that ran a B & M Hydrostick first behind a blown Olds and later behind a blown Chrysler:

It put on an unforgettable show competing against other greats like "Ohio" George Montgomery and "Big" John Mazmanian in the "Gasser Wars"..
I know that some of those old timers are still alive and kicking. For example dragster chassis builder Kent Fuller lives in a retirement community near me. I know that because I saw a beautiful set of headers on a roadster recently and when I asked who built them the answer I got was Kent Fuller. No wonder those headers were such works of art.
