VEGE Remanufactured VCH4CNG 5.7L 350ci CNG Dedicated Long Block Engine

Description

Severe exhaust valve torching and dry gaseous fuel seat recession ruin standard gasoline long blocks converted to compressed gas. The VEGE Remanufactured VCH4CNG CNG Dedicated Long Block Engine solves extreme thermal erosion during an industrial engine rebuild. This 5.7L 350ci 8-Cylinder assembly produces 210HP. Technicians must check intake manifold vacuum fittings for alternative fuel sensor plumbing.

High nickel ASTM A48 Class 35 gray iron forms the seasoned cylinder block and heavy duty cylinder heads. A balanced nodular iron crankshaft rotates inside premium tri-metal copper lead bearings inside this VEGE engine build. Cold cranking draws 175A from standard 12V heavy duty commercial battery systems. Total unrigged weight reaches 455 lbs with dimensions of 29in length, 26in width, 27in height. The stamped steel sump holds 5.0 quarts.

Key Features of VEGE Remanufactured VCH4CNG

Supervisors buy VEGE Remanufactured VCH4CNG CNG Dedicated Long Block Engine units for municipal utility fleets. This commercial long block repower integrates specialized metallurgy to withstand high combustion heat from alternative fuels.

• Stellite faced exhaust valves resist thermal seat erosion under dry gaseous fuel combustion.
• Induction hardened valve seats stop pocket sink during extended stop-and-go transit routes.
• Four bolt iron main caps secure the crankshaft journals under continuous high load.
• The VCH4CNG commercial core uses severe duty roller lifters that prevent lobe galling.
• 0.0016in rod journal clearances preserve protective hydrodynamic oil films under high cylinder heat.
• Plateau honed cylinder bores allow ductile iron rings to seat fast without blowby.
• Multi layer steel head gaskets maintain positive cylinder sealing under intense alternative combustion.

Dynamometer Testing Operational Boundaries

Dynamometer cell tests rate this VCH4CNG long block engine at 210 BHP and 300 ft-lbs of continuous torque at 3200 RPM. Internal oil galleries show 52 PSI at 195°F oil pan thermal stabilization. Exhaust pyrometer thermocouples register 1280°F during continuous high load runs on the water brake absorber unit. Cylinder compression gauges verify 175 PSI across all eight cylinders within 4% balance across both banks. Crankshaft total runout measures under 0.0003in TIR to safeguard copper bearing babbit surfaces under load.

Plant Usability Installation Guidelines

Throttle governor linkage arms require 5 lbs of return spring force to ensure complete idle cutoff. This dedicated alternative fuel long block is NOT engineered for standard unleaded gasoline carburetors, marine inboard racing hulls, or lightweight aircraft conversions.

• Drain break-in motor lubricant and change the spin-on filter element at 500 miles or 30 operating hours.
• Hydraulic roller lifters seat beneath fixed alignment spider trays with zero manual lash adjustment steps.
• Torque cylinder head fasteners in proper progressive spiral sequence to prevent localized gasket fire ring crush.

Crated Delivery Warranty Provisions

Built to match the rigorous VEGE assembly standard, this alternative fuel engine carries a 3-Year 100,000-mile commercial warranty. The timber freight crate encloses the sealed long block, industrial oil pan, timing cover, steel valve covers, oil pickup screen, and authenticated shop dynamometer quality checklist.
