I have a BB in a 69 and only have about 450 miles on the car since the restoration/engine rebuild. I used polygraphite motor mounts, transmission mount, frame to body mounts, and all suspension bushings. The engine was precision balanced before reassembly. I have some vibration although not extreme and wondered if there is a big difference in perceived vibration between standard rubber motor/transmission mounts and the polygraphite/urethane versions. Any input would be appriciated.
