I would say that makes no sense but the car did what it did. Points to something else as the bottleneck

Gravity is my bottleneck now.

After doing some extensive research I pulled the trigger on just about everything I will need to build up a new transmission except a torque convertor. I bought a used mid 70's 727 for $250. I spent about $1400 on everything else I thought I would need. New bands, clutches, steels, bolt in sprag, shift kit, new steel planets, 48re parts to hopefully stuff 6 clutch plates in the forward clutch, and more. Some parts are on back order so I will get those in mid june.

Moving onto the rear axle, I want to update the suspension. I am thinking fabricating two links that follow the same sweep as the stock leaf springs will be the simplest solution. I am not crazy about the idea of a slapper bar system because I think it puts a lot of stress on the springs still and mounts as-well. This will allow me to honestly just keep the stock style suspension and save myself a whole bunch of work. I'm really don't want to have to fabricate a triangulated 4 link or a parallel 4 link w/ panhard for this car. Then I would have to figure out how to make a coil-over work in the car which would be way to much work for this car.

I also need to break out the tape-measure and figure out what the biggest tire i can stuff under the car with some wheel with more backspacing. I really don't feel like modifying the wheel tubs. It might be something I put on my to-do list in a few years.

All for now.

Ditto, run the cal tracs. i love mine.

I've been thinking a lot about this. I am going to pull some inspiration from my 4x4 back-group and do a traditional style torque arm with a shackle to stop the axle wrap. My biggest concern is the torque that will be on the spring mounts especially when i go to a bigger tire. And I don't want all that force going to a single mounting point. If for what ever reason a spring mount fails under extreme loads I think there is a strong potential to rip the axle out from under the car.

I am going to use some 1-1/4" .88" wall DOM with 3/4" heim joins to make my torque arms. It's not as heavy as the 1-1/4" Heims and 2" 1/4" wall DOM I use in my 4x4 but these just have to stop directional loads since the springs are locating the axle. The shackle will allow the torque arm to adjust with the arc of leaf springs so I can run the torque arm mounting location in front of the spring mounts.
