Application

Suitable for all vehicles with L-134 Go Devil engine that have been bored to 0.060" oversize during overhaul. This includes vehicles mentioned in the categories to which this product belongs.

Installation notes

Note: This oversize requires that cylinders have been professionally bored to exactly 0.060" above standard size. Cylinders must be honed with correct surface finish. Check piston-to-cylinder clearance: must be 0.0015 to 0.0020 inch. Ring installation requires a piston ring compressor to prevent damage.

Compatibility

Exclusively for engines bored to 0.060" oversize. NOT compatible with standard size cylinders or other oversizes (.010,.020,.030,.040). Both flathead (L-134) and F-head (F-134) variants use the same rings. Note: always verify actual cylinder dimension after boring before ordering rings.

Historical context

The standard piston diameter of the L-134 Go Devil was originally 3.125 inch (79.375mm). During engine overhaul, cylinders were bored in steps (.010,.020,.030,.040,.060 inch) to remedy wear and breathe new life into the engine.
