VEGE Remanufactured DDA5 4.7L 287ci Premium Grade Long Block Engine

Description

High strength nodular iron anchors the VEGE DDA5 Long Block Engine, delivering 235HP at 4,800 RPM for severe commercial long block repower operations in fleet work trucks. This 4.7L 287 cid V8 produces 295 ft-lbs torque. Technicians must check tone wheel tooth configuration because this variant utilizes an alternate trigger wheel pattern for early computer systems.

Solid ASTM A48 Class 35 cast iron shapes the deep skirt 90° engine block. A nodular iron crankshaft and forged powdered metal rods rotate inside this VEGE engine core. Starter draw measures 165A on standard 12V shop circuits. Dry weight scales at 440 lbs with an unrigged stance of 27in length by 26in width by 28in height. Sump holds 6.0 quarts.

Key Features of VEGE DDA5

Commercial operators buy VEGE DDA5 Long Block Engine units to minimize fleet downtime during an industrial engine rebuild turnaround. Every connecting rod undergoes precision bore resizing and pin bushing replacement for rotational balance.

• Cast aluminum cylinder heads feature hardened valve seats to resist recession under heavy truck duty.
• Single overhead camshafts drive chain driven valvetrain components with minimal friction loss.
• Hypereutectic pistons resist thermal expansion to stop cylinder wall scuffing under heavy towing loads.
• The DDA5 commercial core maintains 0.0016in rod bearing oil clearances under heavy dynamometer loads.
• Hydraulic timing chain tensioners prevent chain whip and timing retard under sudden acceleration.
• Splayed cross bolted main bearing caps lock the rotating assembly into the rigid engine case.
• Multi layer steel head gaskets clamp down to eliminate combustion bore leakage.

Dynamometer Bench Performance Output Metrics

Dynamometer runs record 235HP at 4,800 RPM and 295 ft-lbs torque at 3,200 RPM for this DDA5 long block engine. Gauge monitors record 50 PSI oil gallery pressure at 2,000 RPM at 195°F operating temperature. Cylinder compression gauges verify 175 PSI across all eight cylinders within 4% balance. Crankshaft journal runout measures 0.0003in TIR across intermediate journals. Exhaust gas temperature probes register 1,220°F during extended dyno testing.

Field Usability Scheduled Maintenance Directives

Manual throttle cable linkages require 4 lbs pull force to sweep from idle stop to wide open throttle. Fleet maintenance shops should not choose this heavy duty replacement engine for chassis lacking matched tone wheel computers or vehicles lacking adequate transmission cooling.

• Drain break in oil after 500 miles or 30 operating hours then refill with 5W-30 mineral oil.
• Inspect cam sensor air gap before initial ignition startup to avoid synchronization errors.
• Check cylinder head fasteners in three progressive torque steps up to 90 ft-lbs final setting.

Crate Manifest Standard Warranty Coverage

Supported by the VEGE build standard, this package features a 3-Year or 100,000-mile parts warranty. The rugged wooden shipping crate holds the long block core, oil pan, front timing cover, valve covers, oil pump pickup, plus official plant signed inspection documents.
