Chevy 2.8L V6 Remanufactured Engine – 1985-1987 FWD

Description

Across grueling 10-hour municipal work shifts demanding continuous low-speed stop-start driving, diamond-plateau honed cylinders hold zero oil bypass inside the Chevy 2.8L V6 Remanufactured Engine for 1985 to 1987 front-wheel-drive applications. This iron-head 60-degree V6 package restores mechanical dependability across high-mileage corporate shuttle fleets and commercial passenger sedans.

A dense cast iron engine block features siamesed cylinder bores bored and diamond-honed to a 45-degree plateau crosshatch pattern. A nodular iron crankshaft turns inside tri-metal bearings, transferring energy through forged steel connecting rods to lightweight aluminum pistons. Cylinder block decks meet an Ra 30 micro-inch finish. Engine dry weight measures 352 lbs, with a 4.0-quart transverse stamped steel oil pan.

Key Features of Chevy 2.8L V6

Municipal buyers choose to buy Chevy 2.8L V6 remanufactured engine packages to eliminate chronic oil smoke and restore lost low-end acceleration. Rigorous machine shop standards ensure factory-spec operational clearances across every internal moving assembly.

• 0.0012-inch connecting rod journal clearance eliminates bearing knock under abrupt throttle changes.
• Multi-angle valve jobs improve air-fuel flow across intake ports to boost combustion efficiency.
• Chilled iron hydraulic flat-tappet camshaft resists premature lobe rounding under high spring pressures.
• High-grade steel timing gears maintain precise synchronization between crankshaft and camshaft.
• High-strength composite head gaskets seal water jackets against extreme thermal combustion spikes.
• Chevy 2.8L V6 oil galleries undergo high-pressure fluid flushing to remove all machining debris.
• Micro-polished crank pin journals eliminate frictional drag to preserve fuel efficiency during idle.

Dyno Ratings Operating Pressures

Internal oil pressure operates between 18 and 25 PSI at hot idle, increasing to 45 to 62 PSI during highway travel. The coolant circuit stabilizes block heat from 188°F to 202°F under full passenger loads. Power production tops out at 130 horsepower at 4800 RPM and 160 lb-ft torque at 3600 RPM. An 8.9:1 compression ratio yields 150 to 165 PSI cranking compression, radiating 2,250 BTU per minute.

Transverse Driveline Pilot Interface

A 6-bolt transaxle flexplate flange features concentric centering dowels to mate with GM front-wheel-drive automatic units. Crankshaft endplay measures 0.0035 to 0.0065 inches across thrust surfaces. The front crankshaft snout measures 1.250 inches with a standard single keyway to hold the accessory pulley firmly in place.

Lubrication Guidelines Operational Limits

Force-feed engine oil through the main oil pressure sending port prior to initial ignition to saturate internal journals and rocker pivots. This long block is not engineered for competitive track racing, nitrous systems, marine saltwater applications, or gross vehicle weights exceeding manufacturer specifications.

• Inspect crankcase oil dipstick level and radiator expansion tank volume each shift.
• Drain engine oil and install a new spin-on filter every 3,500 miles.
• Check cooling system hoses, thermostat housing, and drive belts every 12 months.

Warranty Protection Manifest Details

Every engine carries a 3-Year / 100,000-Mile commercial fleet warranty protecting business investments against premature mechanical failure. The shipping crate holds a remanufactured long block unit, new high-flow oil pump, full installation gasket kit, and an authenticated machine shop quality inspection certificate.
