Hi it's nice to here you are back running. I had a 9'J converter in my bird about 10 years ago with a 452 motor and it went 5,100 but me and Brad put it in his Duster with a 500 inch motor and it went 5,500 rpms on the brake. Did some one build the converter for you car? Maybe in two weeks i will see what my car will run good luck to you .
