Small block question

Professor Fate said
Not enough info to hazard a guess, but here's a FACT: You're going to grenade your transmission if you don't sort out your kickdown linkage. The pictured adjustment is WAAAY off.
I'm willing to bet that throttle linkage isn't opening the carb all the way, either. The geometry looks off.
Just mentioning it for what it's worth; take it or leave it.

I’m asking for advice and anything you guys are willing to share, I will take and leave nothing. I’ll look into the linkage, thank you for offering your advice! The trans is the only thing not worked so I’m expecting it won’t last. What would you recommend?
