I have been using Copes RMVB wo/brake and no issues here. I will say thou that the A&A valve body with brake that the Cope replaced had a bit firmer shift. When i get another for the Hemi combo, i really would like to try the Griner from Keith. Have always heard good about the Griners.
Griner has lots of line pressure and is quite quick reacting, very handy on a 400 pro tree.
You being mainly a street driver and occasional test and tuner and non racer, not sure what benefit you would see, it won’t make the car any faster.
