Built on Real Engine-Rebuilding Experience

Decades before today’s engine shops trusted our equipment, Tony was already deep in the craft — rebuilding motors, machining blocks, and pushing for better precision.

A local newspaper once featured him as a standout young machinist, noting his drive, attention to detail, and obsession with doing things the right way. That same passion would eventually shape our company’s values.

Today, that commitment lives on in every machine we sell, every customer we support, and every shop we help succeed.
