This box is in a 47 Ford Coupe with a SBC using the type II pump. Prior to installing this box, I had a 605 box installed. The 605 had leaks and occasionally stuck. Not good. I was hoping this box would solve my problem.

Does anyone have any input on what is causing this problem?
i installed same box on 63 chevy2 and have same problem. did you figure out what was causing the bind?
