Description

The severe commercial payload requires the VEGE Remanufactured VCM9 5.7L 350ci Heavy Duty Long Block Engine and its reinforced iron architecture. Command massive low-end torque during aggressive towing scenarios. This build utilizes a precision machined 5.7L block to deliver 250 HP reliably.

Key Features of VEGE Remanufactured VCM9 5.7L 350ci

• Seasoned 350 CID Cast Iron Block (4-Bolt Main): Establishes a highly rigid foundation to prevent structural flexing under extreme heavy duty towing loads.
• Cast Iron Cylinder Heads: Dissipates combustion chamber heat rapidly to prevent detonation while pulling heavy trailers.
• Hydraulic Roller Camshaft: Eliminates flat-tappet wear concerns while delivering a broad and highly usable mid-range torque curve.
• Hypereutectic Pistons (9.0:1 Compression): Manages thermal expansion effectively to maintain optimal cylinder wall clearance on 87 octane pump gas.
• Pre-Installed Oil Pan & Timing Cover: Seals the long block securely from the factory to eliminate tedious bottom-end assembly steps.
