VEGE 331F 2.4L 2389cc Car Truck Long Block Remanufactured Crate Engine

Description

Upgrade aging utility fleet vehicles with the VEGE 331F Remanufactured Crate Engine 2.4L 2389cc car truck long block configuration. This remanufactured four-cylinder powerplant produces 155 brake horsepower at 5,600 RPM for dependable commercial service. Multi-port electronic fuel injection feeds calibrated gasoline charges straight into intake runners with zero unburned fuel puddling across variable throttle inputs.

A deep-skirt cast iron engine block provides structural rigidity for a balanced forged steel crankshaft anchored by four-bolt ductile iron main caps. Cylinder walls receive computer-controlled plateau honing to a 3.50-inch bore 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 journal bearings while dry weight reaches 348 lbs.

Key Features of VEGE 331F

Fleet mechanics choose to buy VEGE 331F crate engine units to repower hard-working light trucks and cargo chassis. Comprehensive remanufacturing brings each casting back to original factory tolerances and deck squareness for long-term road service.

• Twelve-valve single overhead camshaft geometry optimizes intake air velocity for low-speed hauling torque.
• Induction-hardened exhaust valve seats eliminate recession under continuous high-temperature driving conditions.
• Precision-ground camshaft lobe profiles maintain accurate valve opening duration across operating RPM bands.
• Multi-layer steel cylinder head gaskets maintain combustion chamber seals under heavy vehicle payload demands.
• High-volume internal oil pumps furnish continuous pressurized oil flow to overhead rocker arm shafts.
• Factory-standard 331F replacement engine casting points mate straight to original equipment motor mount brackets.
• Alloy steel double-row timing chains eliminate timing stretch to protect exact valvetrain synchronization.

Dynamic Dyno Torque Metrics

This 2.4-liter engine operates across an active 1,500 to 5,600 RPM power band. Peak output registers 155 brake horsepower at 5,600 RPM while maximum torque reaches 160 lb-ft at 4,400 RPM for confident grade climbing. The camshaft profile specifies 206 degrees duration at 0.050-inch lift with 0.400 inches of gross valve lift. Recommended fuel is standard 87-octane pump gasoline. Warm idle manifold vacuum holds 18 in-Hg while hot oil pressure maintains 45 to 60 PSI at 2,500 RPM.

Chassis Crossmember Drop Clearance

The rear block interface bolts straight to factory five-speed manual transmissions and automatic gearboxes using precision alignment dowels. A neutral-balance flywheel unit isolates driveline vibration under heavy acceleration. Factory motor mount positions seat the oil pan flat between frame rails, maintaining complete clearance above steering linkages and chassis suspension crossmembers without metal modifications.

Break In Maintenance Protocol

Pre-lube internal oil galleries using an external pressurized lubrication canister before initial ignition cranking. Charge the crankcase with SAE 10W-30 break-in oil containing elevated zinc additives to bed in piston rings against cylinder walls. This remanufactured engine package is not engineered for aftermarket turbocharger boost levels, nitrous oxide foggers, or marine inboard propulsion use.

• Operate the engine between 1,800 and 2,200 RPM for 20 minutes to seat rotating group bearings.
• Drain the initial break-in motor oil and install a new spin-on filter at the first 500 miles.
• Schedule regular oil and filter changes every 3,000 miles or every 6 months of severe service.

Verified Crate Manifest Terms

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