VEGE 331M 2.4L 2389cc Heavy Duty Long Block Remanufactured Crate Engine

Description

Harness continuous hauling torque through the VEGE 331M Remanufactured Crate Engine 2.4L 2389cc heavy duty long block package. This remanufactured four-cylinder engine generates 155 brake horsepower at 5,600 RPM for severe commercial service. Multi-port electronic fuel injection feeds calibrated gasoline charges straight into intake runners with zero unburned fuel waste across all operating conditions.

A thick-wall cast iron block casting anchors a balanced forged steel crankshaft supported by four-bolt ductile iron main caps. Cylinder bores receive diamond plateau honing to 3.50 inches matched to a 3.78-inch stroke length. Hypereutectic aluminum pistons establish a 9.2:1 compression ratio above forged steel connecting rods. A five-quart baffled steel oil pan protects bearings from oil starvation while dry weight totals 350 lbs.

Key Features of VEGE 331M

Commercial contractors choose to buy VEGE 331M crate engine units to repower severe-service utility trucks and cargo haulers. Comprehensive remanufacturing brings each casting back to original factory tolerances and deck squareness for long-term commercial duty.

• Twelve-valve single overhead camshaft geometry optimizes intake air velocity for low-speed pulling torque.
• Induction-hardened valve seat inserts resist valve face erosion under prolonged high-temperature hauling tasks.
• Precision-ground camshaft lobes maintain smooth valve motion without unwanted valvetrain harmonics.
• Multi-layer steel cylinder head gaskets maintain combustion chamber seal under severe engine heat.
• High-output internal oil pumps maintain pressurized lubricant delivery to overhead rocker arm shafts.
• Standardized 331M heavy duty long block specifications preserve direct bolting to original engine brackets.
• Alloy steel double-row timing chains eliminate timing stretch to protect exact valve timing synchronization.

Dynamic Dyno Torque Metrics

This 2.4-liter engine operates within a dependable 1,500 to 5,600 RPM band. Peak brake horsepower hits 155 HP at 5,600 RPM while maximum torque reaches 160 lb-ft at 4,400 RPM for solid hauling capability. The camshaft profile specifies 206 degrees duration at 0.050-inch lift with 0.400 inches of valve lift. Fuel requirements call for 87-octane pump gasoline. Warm idle vacuum pulls 18 in-Hg while hot oil pressure registers 45 to 60 PSI at 2,500 RPM.

Chassis Crossmember Drop Clearance

The rear bellhousing pattern bolts straight to factory rear-wheel-drive five-speed manual transmissions and four-speed automatics. An internal neutral balance flywheel eliminates driveline vibrations under load. Factory motor mount positions place the deep-sump oil pan straight between steering links and front suspension crossmembers, preserving original chassis ground clearance without mechanical modification.

Break In Maintenance Protocol

Pre-lube the engine block with an external oil priming unit to coat all bearings before first startup. Fill the oil pan with SAE 10W-30 break-in oil containing high levels of zinc anti-wear additives. This remanufactured long block is not engineered for high-boost turbocharger applications, nitrous oxide fogger nozzles, or marine salt water cooling.

• Run the engine between 1,800 and 2,200 RPM for 20 minutes to break in camshaft lobes.
• Drain the initial break-in oil and change the spin-on filter element at the first 500 miles.
• Repeat oil and filter changes every 3,000 miles or every 6 months to maintain internal engine health.

Verified Crate Manifest Terms

A comprehensive 24-Month or 50,000-Mile warranty covers all internal remanufactured mechanical parts against defect. The secured freight container encloses the complete long block engine, sealed oil pan, valve cover, front timing cover, internal oil pump, and a certified dynamometer inspection sheet for shop records.
