• State-of-the-art machines and machining methods are utilized. All components are magnafluxed, inspected, and machined to OEM specifications.
• All Blocks are magnafluxed. Upper and lower counter bores are repaired as needed, the deck is resurfaced and the aligned bore is honed to OEM specifications.
• Cylinder heads are magnafluxed, pressure tested, and new valve guides and new valves are installed in every cylinder head. Valve seats are machined to OEM specifications and then vacuum tested.
• Crankshafts are magnafluxed, straightened if needed, and polished or ground undersized.
• Connecting Rods are magnafluxed new rod bushing installed and machined to OEM specifications.
• All engines and components are assembled and machined in the United States of America. Every engine is machined using state-of-the-art equipment and assembled using precise and repeatable methods. All engine production follows documented lean, high-quality, manufacturing processes and principles.
