VEGE Remanufactured VCK2 7.4L 454ci Heavy Duty Long Block Engine

Description

Burnt exhaust valves and excessive oil consumption from worn valve guides cripple heavy commercial dump trucks on highway grades. The VEGE Remanufactured VCK2 Heavy Duty Long Block Engine eliminates chronic loss of pulling torque during an industrial engine rebuild. This 7.4L 454ci 8-Cylinder big block brute generates 290HP. Technicians must verify oil bypass valve seating before installing oil coolers.

Massive ASTM A48 Class 35 cast iron forms the seasoned four bolt main block and high flow combustion heads. A balanced forged steel crankshaft spins on tri-metal copper lead bearings inside this VEGE engine build. Heavy duty 12V starter motors draw 190A during cold engine turnover. The unrigged dry package weighs 650 lbs across proportions of 31in length, 28in width, 29in height. The deep stamped steel pan holds 7.0 quarts.

Key Features of VEGE Remanufactured VCK2

Municipal fleet directors buy VEGE Remanufactured VCK2 Heavy Duty Long Block Engine packages to repower heavy transport trucks. Every commercial long block repower integrates premium valve train parts and balanced rotating components to withstand continuous governor limit operation.

• Four bolt main caps provide severe duty bottom end crankshaft support under heavy shock loads.
• Heavy duty roller camshaft profiles produce exceptional low RPM torque for extreme gross weight hauling.
• 0.0018in rod journal clearances preserve protective hydrodynamic oil films under high thermal stress.
• The VCK2 commercial core features induction hardened exhaust valve seats to burn unleaded motor fuel.
• Plateau honed cylinder walls allow ductile iron rings to seat fast without bore glazing.
• Double roller steel timing sets prevent timing slack growth during continuous high hour service.
• Stellite faced exhaust valves withstand continuous high thermal cycles without valve seat recession.

Dynamometer Performance Test Benchmarks

Dynamometer cell testing rates this VCK2 long block engine at 290 BHP and 410 ft-lbs of continuous torque at 3200 RPM. Main oil galleries deliver 55 PSI at 195°F oil pan thermal equilibrium. Exhaust gas thermocouple probes register 1240°F during sustained max load cycles on the water brake absorber unit. Compression testing confirms 175 PSI across all eight cylinders within 3% balance across both cylinder banks. Crankshaft total runout measures under 0.0003in TIR to preserve heavy duty main bearing shells under load.

Commercial Mechanical Chassis Parameters

Throttle governor linkage arms require 5 lbs of return spring force to ensure complete idle cutoff. This 454ci commercial cast iron engine is NOT engineered for lightweight foreign passenger cars, marine ski boats requiring brass core plugs, or unbaffled dry sump racing chassis.

• Drain break-in motor lubricant and replace spin-on oil filter elements at 50 hours or 500 miles.
• Set hydraulic roller lifters to zero lash plus one-half turn down during static valve pre-assembly adjustment.
• Retorque cylinder head fasteners after initial engine thermal warm up cycles to maintain fire ring clamping.

Crate Manifest Warranty Terms

Engineered to meet the stringent VEGE assembly standard, this heavy duty unit includes a 3-Year 100,000-mile parts warranty. The timber freight crate encloses the long block, deep commercial oil pan, timing cover, steel valve covers, oil pickup screen, and authenticated shop dynamometer test sheet.
