Chevy 350 5.7L 2 Bolt Main V8 Remanufactured Engine – 2000-2002

Description

Suppress harmonic crankshaft vibration and eradicate main bearing journal scoring under 60 PSI oil gallery fluid pressure during demanding multi-stop municipal transit route cycles using this Chevy 350 5.7L Remanufactured Engine. Built for 2000 to 2002 fleet platforms, this Gen 1e Vortec unit features hydraulic roller cam actuation and two-bolt main architecture for continuous regional transit service.

Cast from high-nickel gray iron, this engine block features an Ra 32 micro-inch deck surface finish that maintains multi-layer steel combustion seals under high thermal loads. Precision-ground nodular iron crankshaft journals spin on tri-metal copper-lead bearings, while forged powdered metal connecting rods carry graphite-coated hypereutectic pistons inside diamond honed 45-degree crosshatch cylinder bores. Line-honed bearing tunnels eliminate friction. Dry weight equals 435 lbs with a five-quart oil sump capacity.

Key Features of Chevy 350

Fleet operators buy Chevy 350 remanufactured engine packages to sustain demanding schedule routes without unpredicted mechanical downtime. Each production run adheres to strict AERA machining tolerances to maintain factory operational performance.

• 0.0015 inch main bearing oil clearances stabilize hydrodynamic fluid wedges during heavy hauling.
• Multi-layer steel cylinder head gaskets withstand 195 PSI cranking compression under sustained throttle.
• Hydraulic roller lifters reduce valvetrain friction across continuous highway transport duty.
• High-flow gerotor oil pump maintains 55 PSI cruising lubrication inside critical galleries.
• Precision balanced Chevy 350 crankshaft rotating group limits internal vibration under peak torque loads.
• Induction-hardened intake and exhaust valve seats prevent seat recession during continuous operation.
• Powdered metal valve guides hold 0.0012 inch stem clearances to control oil lubricant loss during operation.

Dynamic Oil Pressure Thermal Metrics

Operating parameters require 20 to 25 PSI hot idle pressure and 50 to 70 PSI hot cruise pressure under load. Operating thermostat regulation maintains coolant heat between 185°F and 200°F during vocational service cycles. Dyno-verified output reaches 255 continuous horsepower at 4,600 RPM and 330 lb-ft torque at 2,800 RPM. A 9.4:1 compression ratio operates within 185 to 195 PSI cylinder pressure thresholds. Radiator circuits reject 3,800 BTU/min heat during severe commercial fleet operations across regional freight corridors.

Vortec Crankshaft Driveline Alignment Specs

The one-piece rear main crankshaft flange incorporates a standard 6-bolt flexplate attachment circle with a 2.500-inch register diameter. Crankshaft snout diameter measures 1.248 inches with standard woodruff key retention for harmonic balancer location. Radial dial indicator verification confirms total crankshaft endplay between 0.003 and 0.007 inches. Precision-ground pilot hub bores seat commercial automatic torque converters without radial runout.

Lubrication Priming Service Protocol Rules

Pre-lubricate oil galleries with an external pressure tank before initial ignition to coat all bearing surfaces. Fill crankcase with SAE 30 high-zinc break-in lubricant and bleed cooling system air pockets under vacuum. Not engineered for marine salt water service, forced induction turbocharger systems exceeding 6 PSI boost, or gross vehicle weights exceeding 12,000 lbs.

• Change initial crankcase oil and spin-on filter after the first 500 miles.
• Inspect serpentine belt tensioner and cooling lines every 5,000 miles.
• Perform oil changes with synthetic blend lubricant every 3,000 miles.

Commercial Powertrain Warranty Crate Details

Protected by a 3-Year / 100,000-Mile commercial fleet warranty against structural casting defects. Crated package includes remanufactured long block engine, high-volume oil pump, oil pump pickup screen, complete engine install gasket set, spark plug seal set, pre-lube instruction sheet, and dyno quality control sign-off documentation.
