Checking the ring's 'end gap.' This needs to be filed to proper spec on performance engines. This gap actually closes as the engine heats up. Therefore, the hotter the engine's combustion chamber is (note-NOT water temperature,) the more gap (at room temperature) is needed. There are charts that give ring expansion specs, for instance a turbocharged motor needs much more ring end gap than a normally aspurated motor. On this 350 engine that is bored .030, we will start with an oversize ring set (.035) that will give us plenty to work with. Because of this ring expansion, IMHO 'gapless rings' are just a sales gimmick and a waste of the extra money that they cost.
