VEGE Remanufactured DFAE 4.6L 281ci Multi Purpose Long Block Engine

Description

Plastic timing chain tensioner arm gasket blowouts drop oil pressure and create cam guide rattle in delivery vans. The VEGE Remanufactured DFAE 4.6L 281ci Multi Purpose Long Block Engine eliminates modular timing slap through an industrial engine rebuild. This 4.6L 8-Cylinder SOHC build develops 220HP, but mechanics must inspect cylinder block oil gallery restrictors.

Constructed around an ASTM A48 Class 30 gray iron block, this VEGE engine core utilizes aluminum 2-valve heads and an induction-hardened cast iron crankshaft. Cold starter draw pulls 155A at 12V. Dry weight registers 480 lbs inside 28in length, 28in width, 27in height dimensions with 6.0 quarts oil capacity.

Key Features of VEGE DFAE

Commercial fleet buyers purchase VEGE Remanufactured DFAE 4.6L 281ci Multi Purpose Long Block Engine units to restore delivery vans to dependable service. Cast iron timing tensioners prevent internal oil bleed-down to keep overhead cam chains under proper tension during morning cold starts.

• Displacement measures 281ci utilizing a 3.552in bore and 3.543in stroke rotating assembly.
• Cast iron timing tensioners eliminate oil pressure bleed-down and timing chain guide slap.
• Full-depth steel spark plug thread inserts prevent high-pressure blowout failures permanently.
• Micro-finished overhead camshaft journals minimize friction inside the precision aluminum towers.
• DFAE commercial core alignment boring ensures true crankshaft rotation under heavy pulling conditions.
• Hydraulic lash adjusters provide zero-maintenance valvetrain operation throughout engine life.
• Multi-layer steel head gaskets lock high combustion pressures inside cylinder bores under load.

Test Bench Dyno Limits

Testing on every single DFAE long block engine guarantees factory-spec power delivery. The assembly achieves 220HP at 4750 RPM and 290 ft-lbs torque at 3500 RPM. Sump oil gallery pressure holds 52 PSI hot at 195°F operating temperature. Cylinder compression verifies 175 PSI across all cylinders with 3% variance. Crank journal runout limits to 0.0003in TIR. Steady exhaust gas temp settles at 1220°F under dyno loading.

Integration Demands Maintenance Guidelines

Throttle body linkage pull measures 5 lbs force. This SOHC 2-valve modular unit is NOT suited for 3-valve or 4-valve modular harness applications, direct-injection computer platforms, or transverse front-wheel-drive sedans.

• Flush break-in engine oil and replace the filter element after 500 highway transit miles.
• Inspect front accessory drive belt tensioner alignment after the first 100 hours of run time.
• Check cam cover perimeter fastener torque to 8 ft-lbs following initial thermal normalization runs.

Warranty Statement Shipping Hardware

Protected under the dependable VEGE assembly standard, this remanufactured unit features a 3-Year 100,000-mile commercial warranty. The sturdy transport crate contains the long block engine, oil pan, valve covers, timing cover, oil pump with screen, and signed quality inspection sheet.
