Don’t do that I know that these cars sometimes gets the best of you but you will figure it out as for the motor running and the bearing issue it will still run good not always dose that cause problems. I would have to leally look at it to see what is going on. Maybe a pressure plate issue its hard to say. I would change it out for a 8 inch clutch setup and do away with the 7 1/2 since it is getting hard to find them now.
