Got the motor torn down(1955 235) and found it had been bored .040 over. Motor was rebuilt truck wrecked, motor pulled and has set in a barn for 40+ years.I am ready to clean up the cyls (some surface rust). My Question is are 180 grit stones to aggresive for just a clean up on the cyls. I also have 280 grit stones. There is just a slight ring groove, you can't even feel it with a finger nail. THANKS in advance for any replies!!!
