VEGE Remanufactured DFAX 4.6L 281ci Special Edition Long Block Engine

Description

Worn hydraulic roller followers and timing chain slap trigger sudden misfire codes across commercial pursuit sedans. The VEGE Remanufactured DFAX Special Edition Long Block Engine eliminates catastrophic valvetrain failure during an industrial engine rebuild. This 4.6L 281ci 8-Cylinder SOHC powerplant outputs 240HP. Technicians must check front timing cover seal concentricity before tightening perimeter cover bolts.

Deep skirt ASTM A48 Class 35 cast iron forms the rigid engine block beneath precision resurfaced aluminum cylinder heads. A micro polished nodular iron crankshaft spins on tri-metal copper lead bearings inside this VEGE commercial core. Electrical starter units draw 165A across 12V starter circuits during cold cranking. Total dry unrigged mass reaches 465 lbs with dimensions of 28in length, 27in width, 27in height. The stamped steel sump holds 6.0 quarts.

Key Features of VEGE Remanufactured DFAX

Fleet managers choose to buy VEGE Remanufactured DFAX Special Edition Long Block Engine units to power critical service vehicles. Every commercial long block repower integrates upgraded valve springs and renewed timing components to deliver dependable high RPM pursuit power.

• Performance improved combustion chambers increase airflow filling across broad highway speed bands.
• Full thread spark plug port inserts eliminate spark plug blowout failures under heavy throttle loads.
• Steel backed nylon timing chain guides resist fracturing under severe highway patrol pursuit cycles.
• Cross bolted six bolt main bearing caps provide outstanding bottom end crankshaft stability under load.
• The DFAX engine core features hydraulic roller followers that reduce camshaft friction and wear.
• 0.0014in connecting rod journal clearances maintain protective oil wedge films under continuous thermal loading.
• Multi layer steel cylinder head gaskets maintain positive seal integrity under continuous fleet hauling.

Dyno Test Standards Performance Data

Dynamometer cell tests rate this DFAX long block engine at 240 BHP and 295 ft-lbs of torque at 4200 RPM continuous test loading. Main oil gallery sensors record 50 PSI at 195°F oil pan thermal stabilization. Exhaust runner probes reach 1220°F during sustained continuous test runs on the water brake absorber unit. Dynamic compression testing displays 180 PSI across all eight cylinders within 3% balance across both cylinder banks. Crankshaft total runout measures under 0.0003in TIR to protect main bearing babbit surfaces under load.

Plant Usability Installation Guidelines

Throttle body linkage cables require 4 lbs of return spring resistance to guarantee positive idle closing. This Modular 4.6L V8 powerplant is NOT engineered for transverse front-wheel drive platforms, marine jet drives, or vintage carbureted hot rods lacking electronic ignition controls.

• Flush out initial break-in petroleum motor oil and change the filter at 500 miles or 30 operating hours.
• Hydraulic lash adjusters seat inside cylinder heads with zero manual valve lash adjustments required.
• Torque cylinder head torque-to-yield fasteners using specified angle rotation increments without subsequent hot retorque passes.

Freight Manifest Warranty Coverage

Constructed in strict accordance with the VEGE assembly standard, this replacement long block includes a 3-Year 100,000-mile parts warranty. The timber freight crate encloses the long block, stamped steel oil pan, front timing cover, composite valve covers, pickup tube screen, and signed dynamometer test documentation.
