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

Description

Compacted graphite cast iron reinforces the VEGE VCFA Remanufactured Crate Engine in 5.7L 350ci marine industrial trim. This remanufactured small-block V8 produces 260 brake horsepower at 4,600 RPM and 350 lb-ft torque at 3,200 RPM. Built for continuous-duty watercraft and stationary industrial pumps, this long block sustains high load demands without internal component fatigue.

Selected heavy-duty cast iron cylinder blocks undergo ultrasonic structural inspection, line boring, and plateau honing to 4.000-inch standard finished bore diameters. A remanufactured forged steel crankshaft rotates inside four-bolt main bearing journals secured with high-tensile fasteners. Forged steel connecting rods attach to hypereutectic aluminum pistons with corrosion-resistant coatings. This unit features a 3.480-inch stroke, 9.1:1 compression ratio, 5.0-quart oil capacity, and weighs 440 lbs dry.

Key Features of VEGE VCFA

Marine mechanics buy VEGE VCFA crate engine units to repower inboard watercraft, commercial workboats, and industrial irrigation pumps with dependable hardware. Each remanufactured block features brass freeze plugs and marine corrosion-resistant head gaskets for harsh operating environments.

• 1.94-inch intake and 1.50-inch exhaust stainless steel valves resist thermal corrosion under extended high-throttle operation.
• Brass core expansion plugs eliminate corrosion leaks caused by continuous raw-water cooling systems.
• 0.435-inch intake lift hydraulic flat tappet marine camshafts promote high torque output at low cruising RPM.
• 4.000-inch bore cylinders feature stainless steel top piston rings to handle sustained wide-open-throttle loads.
• Four-bolt cast iron main caps prevent crankshaft journal deflection during continuous industrial pumping.
• Marine-grade circulating water pump gaskets maintain fluid containment under severe thermal expansion cycles.
• One-piece Viton rear main seals prevent crankcase oil loss into inboard bilge compartments.
• VEGE VCFA industrial blocks feature precision deck surfaces to guarantee uniform compression across all cylinders.

Continuous Duty Dyno Specifications

The hydraulic flat tappet marine camshaft features 206 degrees intake and 212 degrees exhaust duration at 0.050-inch valve lift with a 112-degree lobe separation angle. This marine cam profile generates 16 in-Hg manifold vacuum at 700 RPM, maintaining stable idle and throttle transition. Developing 350 lb-ft peak torque at 3,200 RPM, this engine runs on standard 89-octane marine pump gasoline. Calibrated oil passages and a high-volume oil pump maintain 45 to 65 PSI hot oil pressure under continuous wide-open throttle running.

Inboard Marine Transmission Fitment

The small block Chevrolet bellhousing flange attaches straight to Velvet Drive, BorgWarner, and ZF marine transmissions. Factory side engine mount pads bolt to standard marine stringer mounts, while the stamped steel marine oil pan clears inboard hull stringers and bilge pumps without hull interference or fiberglass modification.

Break In Maintenance Schedules

Installers must pre-lube the engine using an external pressure priming tank to fill all oil galleries prior to initial ignition. Use high-zinc SAE 30 marine break-in oil during the first operating hours to coat the flat tappet camshaft lobes. This engine is not engineered for automotive closed emissions systems, supercharging exceeding 5 PSI, or dry exhaust headers.

• Drain initial break-in oil and change the spin-on oil filter after the first 25 operating hours.
• Replace engine oil and spin-on marine filter elements every 100 operating hours or every season.
• Inspect ignition distributor timing and seawater pump impeller condition every 12 months in service.

Warranty Terms Manifest Breakdown

VEGE protects this marine industrial engine with a 12-Month unlimited-hour commercial limited warranty package. The heavy timber shipping crate contains the assembled long block, stamped valve covers, front timing cover, marine oil pan, oil pump, balance certificate sheet, and marine installation instruction manuals for dependable vessel repower operations.
