Our engine block honing services are performed on a Rottler H85AXY, one of the most accurate and rigid CNC honing machines in the industry. This allows us to achieve exceptional bore geometry, surface finish, and repeatability on every block we touch.

We hone all engine blocks, from street and performance builds to high-end racing applications, including Pro Stock Motorcycle blocks. Every block is measured, mapped, and honed to exact specifications to ensure optimal ring seal, reduced friction, and maximum power potential.

What truly sets us apart is experience. With decades of hands-on racing and engine-building knowledge, we understand that perfect numbers on paper mean nothing unless they translate to real-world performance. Our honing process is tailored to the specific application, piston, ring package, and intended use—because no two builds are the same.

Whether you’re chasing longevity, horsepower, or championship-level consistency, your block will leave our shop dead straight, round, and ready to perform at the highest level.
