In my area in the late '80s/early '90s it was commonplace for any kind of "built" musclecar to have a manual valve body if it was automatic. We're talking 12, 11, 10 second street cars here. No one really considered it a "race only" part.
Now when you say Pro Street I think of back halved, full cage cars...which nowadays better do at least 8s or its a poser/show poodle.
