This was the Revell 'Visible V8', first released in 1958. https://macsmotorcitygarage.com/revisiting-the-visible-v8/

While fairly realistic in function, the Visible V8 is not a replica of a specific production engine, though it most resembles an early Cadillac or Studebaker V8.

...but that transmission definitely looks like the early 4-speed Hydramatic: http://www.1954advance-design.com/Hydra-Matic-rebuild/index....
