- Additional Oversize/undersize options may be available – message LowPricedAutoParts your measured bore diameter and crank journal sizes before ordering to confirm options and best fit
- Professional machining and installation strongly recommended – verify cylinder bore, crank journals, and clearances (e.g., typical piston-to-wall 0.002–0.004", rod/main bearing clearances per common rebuild guidelines—confirm with piston/bearing manufacturer specs) – not a drop-in kit for worn engines without blueprinting
