VEGE Remanufactured DFM8 4.6L 281ci Premium Grade Long Block Engine

Description

Thread shear on aluminum spark plug ports creates sudden combustion loss in commercial delivery vans. The VEGE Remanufactured DFM8 4.6L 281ci Premium Grade Long Block Engine eliminates catastrophic plug ejection through a commercial long block repower. This 4.6L 8-Cylinder SOHC build makes 220HP, but mechanics must verify Windsor versus Romeo valve cover bolt counts before installation.

Cast from ASTM A48 Class 30 gray iron, this VEGE engine core pairs with aluminum 2-valve cylinder 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 inside the rear sump.

Key Features of VEGE DFM8

Municipal managers buy VEGE Remanufactured DFM8 4.6L 281ci Premium Grade Long Block Engine assemblies to keep public service fleets operational without expensive new vehicle purchases. Full-depth steel inserts in every spark plug bore prevent combustion pressure blowouts during persistent high-load highway patrol operations.

• Displacement measures 281ci utilizing a 3.552in bore and 3.543in stroke rotating assembly.
• Full-depth steel spark plug thread inserts prevent high-pressure blowout failures permanently.
• Cast iron timing tensioners replace fragile composite units to eliminate timing chain guide slap.
• Micro-finished overhead camshaft journals minimize friction inside the precision aluminum towers.
• DFM8 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.

Hot Cell Verification Data

Testing on every single DFM8 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.

Bay Constraints Maintenance Schedules

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.

• Drain break-in motor oil and install a fresh oil filter after the initial 500 service 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

Built under strict VEGE assembly standard protocols, this remanufactured powertrain includes a 3-Year 100,000-mile commercial warranty. Uncrating reveals the remanufactured long block core, oil pan, timing cover, cam covers, oil pump pickup screen, and certified test sheet.
