Our shop provides complete cylinder head machining and rebuilding solutions for street, performance, and racing applications.

Your crankshaft is the heart of your engine’s rotating assembly — and precision matters at every thousandth of an inch. Using precision equipment we inspect, grind, polish, and balance crankshafts for smooth, reliable engine performance.


Built with precision. Tested for perfection. Ready for performance.
Every precision-machined component deserves expert assembly. Our engine assembly service combines decades of experience with meticulous attention to detail to deliver engines that are balanced, sealed, and ready to perform — whether on the street, strip, or track.
Unlike chassis dynos that measure power at the wheels, our engine dyno measures true crankshaft horsepower and torque.
It eliminates drivetrain losses, giving you precise data on the engine itself. We can dial in timing, fueling, and operating ranges in a controlled environment before installation — reducing risk and saving time on final tuning.
