Chevy 2.8L V6 Remanufactured Engine – 1987-1989 FWD

Description

High-nickel cast iron block architecture absorbs extreme combustion pressure spikes while hypereutectic aluminum pistons resist thermal expansion during grueling vocational work truck operation in the Chevy 2.8L V6 Remanufactured Engine for 1987 to 1989 front-wheel-drive platforms. This multi-port fuel-injected V6 delivers refined throttle response and consistent fuel efficiency across commercial delivery applications.

A rigid high-nickel cast iron block is line-honed along the main bearing journals to ensure straight crankshaft rotation. The nodular iron crankshaft turns inside tri-metal bearings, driving forged I-beam rods and graphite-coated pistons. Deck surface finish measures an Ra 30 micro-inch profile. Complete engine dry weight totals 358 lbs, paired with a 4.0-quart front-wheel-drive oil pan.

Key Features of Chevy 2.8L V6

Commercial transport managers choose to buy Chevy 2.8L V6 remanufactured engine assemblies to restore dependable power to frontline fleet vans. Advanced machine shop techniques maintain exact running clearances across all critical moving components.

• 0.0013-inch connecting rod clearance minimizes friction while maintaining robust oil film strength.
• Multi-angle intake and exhaust valve seats provide positive sealing under continuous heat cycles.
• Billet-ground camshaft delivers smooth idle characteristics and crisp throttle response off idle.
• Multi-layer steel composite head gaskets maintain coolant and oil isolation under high loads.
• Hydraulic flat-tappet lifters maintain zero lash for quiet and durable valvetrain operation.
• Chevy 2.8L V6 high-volume oil pump prevents upper valvetrain oil starvation during high-idle runs.
• Centrifugally cast iron cylinder walls diamond-honed to a 45-degree angle ensure rapid ring break-in.

Operational Limits Output Metrics

Engine oil pressure measures 20 to 25 PSI at hot idle and 50 to 65 PSI at 2500 RPM highway cruise. The internal cooling passages maintain engine block temperatures between 190°F and 205°F. Total power output reaches 130 horsepower at 4500 RPM and 160 lb-ft torque at 3600 RPM. An 8.9:1 compression ratio yields 150 to 165 PSI cranking compression, transferring 2,300 BTU per minute.

Transverse Flange Dampener Specs

A precision-machined 6-bolt flexplate flange aligns with GM front-wheel-drive transaxles without radial runout. Crankshaft endplay measures within 0.003 to 0.007 inches across thrust bearing surfaces. The front snout measures 1.250 inches with a machined Woodruff keyway to locate the harmonic dampener, sealed with a high-temperature front crank seal.

Priming Instructions Usage Disclaimers

Prior to starting, prime the engine lubrication passages using an external pressure pump to ensure oil reaches all cam bearings and rocker arms. This engine is not engineered for forced induction systems, alcohol race fuels, marine applications, or commercial loads exceeding factory gross vehicle weight ratings.

• Examine oil dipstick level and engine coolant level each shift.
• Change engine oil and install a fresh oil filter every 3,500 miles.
• Inspect cooling fan operation, radiator hoses, and serpentine drive belts every 12 months.

Commercial Warranty Package Manifest

Every remanufactured unit includes a 3-Year / 100,000-Mile commercial fleet warranty protecting vocational investments against defects. The heavy-duty shipping container includes a remanufactured long block, replacement oil pump, full engine installation gasket set, and a certified quality control report with recorded bearing clearances.
