LowPricedAutoParts Engine Rebuild Kit for 1968-1970 Buick Chevrolet Oldsmobile Pontiac Car 4.1L 250 Inline-6 | .030" Oversized Pistons and Premium Rings | Standard Size Rod and Main Bearings
Engine rebuild kit for 1968–1970 Buick, Chevrolet, Oldsmobile, Pontiac 4.1L 250 inline-6 OHV engines (naturally aspirated; with wide 0.375" rear main seal – verify your engine's rear main seal groove width and VIN/engine code for exact match)
Includes .030" OVERSIZED pistons and premium piston rings (upgraded design for superior sealing and durability in street/stock applications), STANDARD size rod and main bearings, cam bearings, full gasket set, oil pump, and expansion plug kit
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
