"We went in to get some work done on some of our jobs for our auto shop and was treated so well that we have our racing machine work done there. We have had them do a 383, 406, and now a 408 for our race car. The guys at Diamond are always friendly and will take the time to help you along the way.That is why I take all my work to Diamond" - Kevin Magill,
