Sleeve Length and Stroker Engines
Sleeving an engine block is done for two primary reasons. The first is to repair a cracked or otherwise damaged cylinder to save the block. The second is increasing displacement by allowing for a larger bore size. In either case, the sleeving process must be performed carefully to ensure satisfactory results. Careful measurements are required
What Does the 2nd Ring Really Do?
