Building Your Shovelhead with Precision
It's crucial to understand that this cylinder is not a bolt-on, ready-to-run part. To achieve proper ring seal and compression, it must be finish honed and carefully matched to your chosen pistons, which are sold separately. This allows experienced builders to achieve precise tolerances, ensuring maximum power and longevity from their Shovelhead engine. Plan for professional machining to get the best results from this component.
