Description

Premature camshaft lobe wear and loss of oil pressure under 260 lb-ft sustained cargo hauling compromise regional distribution deadlines until induction-hardened components stabilize combustion chamber pressures inside the Chevy 350 5.7L 2 Bolt Main V8 Remanufactured Engine for 1978 to 1980 models. This passenger-side dipstick small-block V8 restores dependable operational power across municipal utility trucks.

A high-nickel cast iron block features reinforced 2-bolt main bulkheads and torque-plate honed cylinder bores. The micro-polished nodular cast iron crankshaft rotates inside tri-metal bearings linked to forged steel connecting rods and hypereutectic pistons. Block decks meet an Ra 35 micro-inch finish. Total dry weight measures 460 lbs, matched with a 5.0-quart right-hand dipstick steel oil pan.

Key Features of Chevy 350 5.7L 2 Bolt Main V8

Commercial fleet buyers choose to buy Chevy 350 5.7L 2 bolt main V8 remanufactured engine assemblies to eliminate chronic power loss and maintain dependable transport schedules. Advanced CNC machining standards preserve exact running clearances across all critical moving components.

  • 0.0014-inch connecting rod bearing clearance prevents journal galling under continuous low-gear pulling.
  • Induction-hardened exhaust valve seats resist thermal recession under sustained highway hauling speeds.
  • Hydraulic flat-tappet camshaft produces smooth idle vacuum and dependable mid-range cargo pulling torque.
  • Precision-ground valve stems seat tight against hardened valve seat inserts to prevent vacuum loss.
  • Heavy-duty composite head gaskets maintain coolant and oil isolation under severe thermal stress.
  • Chevy 350 5.7L 2 bolt main V8 high-volume oil pump prevents upper valvetrain oil starvation during high-idle runs.
  • Centrifugally cast cylinder walls diamond-honed to a 45-degree angle ensure rapid ring break-in.

Operational Pressure Dynamic Ratings

Operating lubrication pressures span 20 PSI at hot idle to 58 PSI during continuous highway cruise speeds. An internal 195°F thermostat maintains engine coolant temperatures between 185°F and 200°F during severe summer work conditions. Certified dynamometer testing registers 170 horsepower at 3800 RPM alongside 265 lb-ft torque at 2400 RPM. An 8.5:1 compression ratio generates 145 to 160 PSI cranking compression, radiating 2,650 BTU per minute.

Longitudinal Driveline Flywheel Specs

The rear crankshaft features a 2-piece rear main oil seal journal and a standard 6-bolt flywheel bolt pattern. Dial indicator inspection verifies crankshaft endplay within 0.003 to 0.006 inches. The 1.250-inch front crankshaft snout carries a single Woodruff keyway to locate the harmonic dampener, supported by a front timing cover seal.

Service Protocols Priming Directive

Technicians must pressure-prime the engine oil passages using an external mechanical priming tool through the distributor hole prior to initial starter engagement. This powertrain unit is not engineered for turbocharging, alcohol race fuel mixtures, marine boat hulls, or gross vehicle weights exceeding manufacturer chassis limits.

  • Inspect oil sump level and coolant reservoir volume before starting work each shift.
  • Drain crankcase lubricant and install a fresh oil filter every 3,000 miles.
  • Inspect distributor cap, ignition rotor, and radiator hoses every 12 months.

Commercial Fleet Warranty Manifest

A comprehensive 3-Year / 100,000-Mile commercial fleet warranty protects commercial capital against material defects and machining anomalies. The shipment crate contains a remanufactured long block unit, high-flow oil pump, complete installation gasket kit, valve cover gaskets, and a signed inspection certificate validating internal bearing clearances.
