VEGE Remanufactured DD65 5.9L 360ci High Output Long Block Engine

Description

Exhaust valve bridge cracking and severe manifold oil vacuum leaks cripple heavy commercial wreckers mid-haul. The VEGE Remanufactured DD65 5.9L 360ci High Output Long Block Engine cures persistent valvetrain failure through a commercial long block repower. This 5.9L 8-Cylinder build develops 245HP, but mechanics must verify external counterweight placement on the torque converter flexplate.

Constructed around an ASTM A48 Class 30 gray iron block, this VEGE engine core houses heavy-duty cast iron heads and a nodular iron crankshaft. Starter draw demands 165A on 12V circuits. Total dry weight measures 475 lbs within 28in length, 26in width, 27in height dimensions requiring 5.0 quarts oil.

Key Features of VEGE DD65

Commercial transport fleets buy VEGE Remanufactured DD65 5.9L 360ci High Output Long Block Engine units to restore heavy towing capacity to service chassis. Heavy-duty cylinder head castings feature thickened deck areas to stop thermal stress fractures between adjacent intake and exhaust valve seats.

• Generous 360ci displacement combines a 4.000in bore with a 3.580in stroke for heavy towing torque.
• Reinforced cylinder head deck regions eliminate cracking between intake and exhaust valve seats.
• Upgraded aluminum plenum belly pan plate prevents vacuum-induced oil consumption leaks.
• Hydraulic roller camshaft lobes eliminate zinc additive dependencies during routine maintenance operations.
• DD65 commercial core precision line-boring guarantees true crankshaft journal rotation under heavy loads.
• Plateau-honed cylinder walls establish immediate piston ring seal without blowby.
• Tri-metal copper-lead bearings absorb abrasive micro-debris to prevent crankshaft journal scoring.

Dyno Test Cell Metrics

Dyno validation confirms mechanical parameters on each DD65 long block engine before shipping. The big displacement V8 develops 245HP at 4400 RPM and 335 ft-lbs torque at 3200 RPM. Oil gallery pressure maintains 55 PSI hot at 195°F oil temperature. Cylinder compression balances out at 170 PSI across all cylinders with 3% variance. Crank runout limits to 0.0003in TIR. Exhaust gas temp tops out at 1260°F under full load.

Operational Exclusions Setup Protocols

Mechanical throttle lever operation needs 5 lbs pull resistance. This Magnum pushrod V8 engine is NOT compatible with neutral-balance 5.2L flexplates, early LA-style intake manifolds, or modern computer-controlled direct-injection platforms.

• Drain break-in motor oil and renew the filter element after 500 highway transit miles.
• Inspect intake manifold belly pan perimeter fasteners after the first 50 operating hours.
• Check cylinder head bolt torque down to 105 ft-lbs following initial thermal normalization runs.

Commercial Protection Included 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, valve covers, oil pump pickup screen, and certified test sheet.
