How do you know what size pistons, piston rings, rod bearings or main bearings. if anyone knows how to choose what sizes to get or if you have redone you own engine and have any tips then just leave a comment and let me know.

The best alternative is to have a machine shop measure it for you.. If the engine has ever been rebuilt or if it is worn out it will prolly need reboring and new larger pistons ordered.
