Noob question 727 really low shift points

Ok so after much ado, I may have saved my transmission yet. Attached is a photo of the linkage and cables attached up at the carb with a decent amount of slack for further adjustment. I video recorded a trial run to upload so I’ll upload that a little later but essentially it’s shiftin now between 30 and 35 for 1 -> 2 and 45 and 50 for 2 -> 3. I don’t think that’s optimal but at this point I’m ecstatic that it’s shifting semi normally. It’s not kicking down so there’s work to be done for sure, but I’m at a better starting point than I was before.

Sounds good so far, but pretty high in the shift points.
I just used a light spring to insure the lever on the trans was pulled all the way forward with zero throttle.
Without a shift kit the trans should be in third by about 20mph.
I think with the shift points so high that is what is messing with your kickdown, and once the shifts are within a normal range it should come back.
You are almost there.:D
