VEGE DCWC 8.1L 496ci Industrial Grade Long Block Remanufactured Crate Engine

Description

Eliminate severe industrial machinery downtime with the VEGE DCWC Remanufactured Crate Engine big-block casting machined for brutal 8.1L 496ci duty cycles. The non-EGR powerplant outputs 340 horsepower at 4,200 RPM and 455 lb-ft torque at 3,200 RPM using multi-point sequential electronic injection. Industrial remanufacturing processes true cylinder decks, align-hone main bores, and test structural integrity.

A thick cast iron block incorporates four-bolt splayed ductile iron main caps that anchor an induction-hardened forged 4340 steel crankshaft. Forged 4340 steel I-beam rods mate with coated hypereutectic pistons to establish a 9.1:1 compression ratio. Cylinder bore measures 4.250 inches while stroke stretches to 4.370 inches. A heavy rear-sump industrial pan retains 6.5 quarts of fluid, setting total dry weight at 762 lbs.

Key Features of VEGE DCWC

Equipment builders buy VEGE DCWC crate engine packages to repower stationary water pumps, commercial generators, and heavy airport ground tugs. Machined cast iron port runner surfaces promote uninhibited fuel flow across continuous throttle pulls.

• 6.5-quart high-capacity oil pan maintains continuous oil pressure under severe commercial operating pitch angles.
• 2.19-inch stainless steel intake valves increase fresh air charge mass into combustion chambers.
• 0.030-inch deck surface milling restores DCWC industrial long block cylinder sealing without leaks.
• 1.72-inch sodium-filled exhaust valves resist extreme heat accumulation under uninterrupted governor-load operations.
• Ductile iron four-bolt main bearing caps withstand elevated combustion pressures without crankshaft deflection.
• Pinned nodular iron harmonic balancer dampens torsional crankshaft pulses during low-speed high-torque drags.
• Multi-layer steel cylinder head gaskets maintain liquid retention across high thermal work cycles.

Dynamic Industrial Camshaft Output Verification

Engineered for continuous work profiles between 1,000 and 4,400 RPM, this big block employs a hydraulic roller camshaft featuring 204 degrees intake and 209 degrees exhaust duration at 0.050-inch lift. Valve lift tops out at 0.485 inches. The motor runs on 87-octane pump gasoline, generating 18 in-Hg intake vacuum. Standard high-volume oil pumps stabilize pressure between 45 and 65 PSI hot throughout extreme work shifts.

Chassis Crossmember Bellhousing Clearance Specifications

The cylinder block features the classic GM big block V8 bolt pattern for pairing with Allison automatics or manual transmissions. Internal neutral balance configurations work with standard six-hole flexplates. Side mounting bosses thread straight to original equipment motor isolation pads, preserving one inch of space between the pan rail and front suspension steer linkages.

Oil Priming Guidelines Service Duty Restrictions

Pressurize the main oil galleys with 15W-40 heavy-duty oil via an external priming pump before turning the ignition switch. This engine is not engineered for marine saltwater exposure, alcohol fuels, or turbocharger setups exceeding factory industrial parameters. Adhere to these mechanical inspection intervals.

• Replace initial oil and spin-on filter element after first 50 miles of run time.
• Exchange synthetic crankcase oil and primary filter every 3,000 miles or 200 operational hours.
• Perform coolant chemical testing and flush cooling chambers every 12 months.
• Torque exhaust manifold fasteners and inspect water jacket plugs after 100 operating hours.

Commercial Warranty Coverage Included Manifest

VEGE backs this heavy remanufactured package with a 24-Month / 50,000-Mile fleet limited warranty. The heavy wooden skid includes the assembled long block, cast iron cylinder heads, stamped valve covers, front timing cover, industrial oil pan, oil pump, and dyno clearance verification sheet.
