Powerglide in 440 dart

My, how the circle turns....

A bit of trivia....

When Pontiac released the GTO in 1964, touted as a performance car [ with a triple two barrel carb option ], it came with a two speed auto trans [ ST300 ]. A two speed, hardly inspiring for performance.

I have an article that shows how to swap the ST300 for a 727 TF!
