Groove-O-Matic Block Ringing Tool

The Groove-O-Matic Block Ringing Tool by ISKY CAMS is a precision instrument designed for engine builders, performance mechanics, and automotive enthusiasts who require accuracy when honing cylinder bores and measuring block deck surfaces. This versatile tool is essential for both high-performance engine assembly and general engine restoration projects.

The Groove-O-Matic tool helps eliminate ring flutter and ensures optimal piston-to-wall clearance during initial startup and break-in. It identifies micro-variations in bore diameter and deck surface geometry that conventional honing equipment may overlook, providing reliable measurements for engine builders.

Engine builders preparing blocks for stroker kits, turbocharger builds, or naturally aspirated high-RPM applications will find this tool indispensable for validating bore consistency. Its compact size and lightweight construction make it easy to use in various settings, whether in a shop or on location.
