VEGE Remanufactured VC15 5.7L 350ci Industrial Grade Long Block Engine

Description

Restore sustained valvetrain efficiency with the VEGE VC15 Industrial Grade Long Block Engine during your next commercial long block repower. This 5.7L 350ci 8-Cylinder engine produces 250HP for severe commercial transport. Machinists must verify torque converter snout diameter against the crankshaft pilot hole because industrial flywheels use two distinct centering bore diameters across application groups.

Heavy duty ASTM A48 Class 35 gray iron casting creates the rigid four-bolt main block structure. This VEGE engine core features an induction hardened nodular iron crankshaft and forged AISI 4140 steel connecting rods. Stellite faced exhaust valves and high nickel valve seats survive heavy heat exposure. The 12V starter draws 180A under full cold compression. Bare dry weight measures 475 lbs with dimensions of 28in length, 26in width, 27in height, and 5.0 quarts oil capacity.

Key Features of VEGE VC15

Fleet directors buy VEGE VC15 Industrial Grade Long Block Engine configurations to complete an industrial engine rebuild with zero mechanical guesswork. Precision boring bars restore cylinder geometry within 0.0002in roundness to ensure instant piston ring break-in.

• A massive 5.7L 350ci displacement base delivers high flat-plane torque for heavy commercial hauling.
• Four-bolt main bearing caps anchor the bottom end to eliminate crankshaft flex during heavy acceleration.
• Hypereutectic aluminum pistons resist thermal expansion scuffing inside close cylinder tolerances.
• The VC15 commercial core valvetrain features hardened pushrods to prevent bending under sustained RPM operation.
• High volume oil pump gears deliver constant pressure to overhead valvetrain components.
• Premium elastomer front and rear crankshaft seals prevent external motor oil leakage across harsh duty cycles.
• Stress relieved cast iron cylinder heads minimize deck distortion during high load heat cycles.

Dynamometer Verification Operational Thresholds

Bench testing proves that each VC15 long block engine generates 250HP and 330 ft-lbs of torque at 4,000 RPM. Technicians maintain a 2,500 RPM continuous load while oil gallery pressure stays between 48 PSI and 62 PSI. Sump oil temperature reads 195°F with exhaust gas temperatures reaching 1,240°F under full load. Individual cylinder compression verifies at 180 PSI with variation among cylinders below 5%. Crankshaft journal runout registers under 0.0003in TIR to stop journal bearing wear.

Field Installation Maintenance Protocols

Mechanical throttle control linkage requires 6 lbs return pull force to avoid unintended open throttle conditions. Do not install this commercial replacement engine into high RPM drag strip cars or marine hulls without wet exhaust manifolds. Fleet mechanics must carry out essential shop maintenance procedures.

• Drop break-in crankcase oil and install a replacement oil filter at 500 miles or 25 run hours.
• Check cold hydraulic lifter pre-load to set zero lash plus three-quarter turn on rocker nuts.
• Retorque cylinder head perimeter bolts to 65 ft-lbs following initial operating thermal cycle.

Crate Manifest Coverage Terms

Assembly methods conform to the high VEGE assembly standard protected by a 3-Year 100,000-mile parts warranty. The timber transit crate contains the remanufactured long block core, steel oil pan, timing gear cover, valve covers, oil pickup tube, and the complete shop quality control sheet.
