VEGE Remanufactured VCFA 5.7L 350ci Marine Industrial Long Block Engine

Description

Marine manufacturing specifications establish the VEGE VCFA Long Block Engine as an outstanding commercial long block repower unit for marine and stationary industrial installations. This 5.7L 350 cid small block V8 creates 260HP at 4,600 RPM. Installers must install marine certified bronze freeze plugs to prevent cooling water jacket corrosion.

Solid ASTM A48 Class 35 cast iron forms the 4-bolt main engine block case. A cast nodular iron crankshaft pairs with heavy beam connecting rods inside this VEGE engine core. Starter draw measures 165A on standard 12V marine circuits. Dry engine weight measures 480 lbs within dimensions of 28in length by 25in width by 27in height. Sump holds 5.0 quarts.

Key Features of VEGE VCFA

Marine mechanics buy VEGE VCFA Long Block Engine assemblies to eliminate workshop backlogs during an industrial engine rebuild job. Brass freeze plugs and marine camshaft grinds ensure long term corrosion resistance and pulling torque.

• Cast iron cylinder heads feature hardened exhaust valve seats to handle continuous marine load.
• A specialized marine camshaft profile prevents water reversion through exhaust valves under idle.
• Durable flat top hypereutectic pistons maintain tight piston to wall clearance under heat.
• The VCFA commercial core maintains 0.0016in connecting rod bearing clearance for oil wedge stability.
• Four bolt main bearing caps provide bottom end structural rigidity against continuous propeller load.
• High output oil pumps supply constant lubrication volume to internal oil passages.
• Multi layer steel head gaskets seal high combustion pressures against block deck faces.

Dynamometer Test Limits Thermal Thresholds

Dynamometer testing confirms 260HP at 4,600 RPM plus 350 ft-lbs torque at 3,000 RPM for this VCFA long block engine. Pressure sensors track 55 PSI oil gallery pressure at 2,000 RPM while maintaining 185°F raw water cooling operating temperature. Combustion chamber compression measures 180 PSI across all eight cylinders within 3% balance. Crankshaft journal runout checks show 0.0002in TIR across main journals. Exhaust pyrometers register 1,220°F during extended test sweeps.

Shop Installation Maintenance Protocol Requirements

Marine throttle linkages demand 5 lbs return spring pull force to ensure positive valve return. Technicians should not install this commercial replacement engine into automotive passenger cars requiring computer controlled exhaust oxygen sensors or automotive emission smog pumps.

• Drain break in oil after 25 operating hours then install 15W-40 four stroke marine oil.
• Inspect brass freeze plugs for water tight seal prior to initial sea trial or test run.
• Check cylinder head fasteners in proper sequence reaching 65 ft-lbs final setting.

Crate Manifest Extended Warranty Coverage

The VEGE build standard includes a 2-Year limited marine and industrial manufacturer warranty. The heavy wooden crate holds the dressed long block core, oil pan, timing cover, valve covers, oil pump pickup tube, plus certified factory inspection sheets.
