VEGE DB40 4.1L 252ci Car Truck Long Block Remanufactured Crate Engine

Description

Featuring 252-cubic-inch displacement block casting, the VEGE DB40 Remanufactured Crate Engine car truck long block package repowers full-size passenger sedans and light pickup trucks. Displacing 4.1L across 252ci in a ninety-degree V6 layout, this motor outputs 125 BHP at 4000 RPM and 205 lb-ft torque at 2000 RPM, restoring effortless low-RPM acceleration and quiet highway cruising manners.

A deep-skirt cast iron V6 engine block houses cylinders bored to 3.965 inches and stroked to 3.40 inches. The rotating group incorporates a balanced even-fire nodular iron crankshaft, drop-forged connecting rods, and hypereutectic aluminum alloy pistons. Cylinder pressure achieves an 8.0:1 compression ratio for regular fuel operation. A 4.5-quart steel wet sump oil pan maintains continuous oil pickup. Total dressed dry weight registers 385 lbs for solid chassis stability.

Key Features of VEGE DB40

Classic car restorers buy VEGE DB40 crate engine packages to recondition vintage full-size passenger vehicles without expensive custom machine shop delays. Each remanufactured long block receives precision deck squaring, line-honed main bearing tunnels, and micro-polished crank journals to eliminate oil burning.

• 3.965-inch cylinder bores feature diamond plateau honing to seat piston rings fast.
• Overhead valve pushrod valvetrain provides twelve valves of high-torque low-RPM induction.
• 43.4mm intake valves and 38mm exhaust valves promote smooth combustion chamber scavenging.
• 58cc combustion chambers eliminate detonation knock when burning standard 87-octane pump gasoline.
• Multi-layer steel head gaskets seal combustion fire rings under heavy towing loads.
• Hydraulic flat tappet lifters inside the VEGE DB40 block maintain quiet valve actuation.
• Even-fire crankshaft cancels reciprocating harmonic vibrations through chassis mounts.
• Stamped steel rear-sump oil pan clears passenger car steering linkages and crossmembers.

Combustion Dynamics Dyno Output Specs

The power curve delivers massive low-end torque between 800 and 4,400 RPM. Peak dynamometer figures reach 125 brake horsepower at 4,000 RPM alongside 205 lb-ft torque at 2,000 RPM. Camshaft duration measures 194 degrees on intake and 202 degrees on exhaust at 0.050-inch lift, alongside 0.405-inch valve lift. The motor runs on standard 87-octane regular pump unleaded gasoline. Intake manifold vacuum pulls 20 in-Hg at a smooth 650 RPM idle. Cruising oil pressure stabilizes between 40 and 62 PSI at 2,200 RPM.

Drivetrain Interface Engine Bay Clearance

The rear bellhousing pattern aligns flush to longitudinal three-speed and four-speed automatic transmissions. An internal neutral balance crank flange connects straight to production torque converter flexplates. Factory cast iron motor mount brackets line up with chassis rubber isolators, preserving three inches of clearance above the front suspension crossmember.

Break-In Protocol Maintenance Parameters

Pre-lube all engine oil passages with a pressurized tank before initial startup to protect journal bearings and lifters. Fill the crankcase with SAE 10W-30 high-zinc mineral break-in oil and bleed trapped air bubbles from heating circuit hoses. This large-bore pushrod V6 motor is not engineered for turbocharging exceeding 5 PSI boost, high-RPM track racing, or unmetered nitrous oxide injection.

• Run motor at 2,000 RPM for 20 minutes to bed in flat tappet camshaft lobes.
• Drain initial break-in lubricant and install a fresh oil filter after the first 500 miles.
• Change conventional crankcase motor oil and inspect cooling lines every 3,000 miles.

Verified Warranty Physical Crate Manifest

A 36-Month / 100,000-Mile nationwide limited warranty provides long-term mechanical protection against defects. The heavy transport crate contains the remanufactured long block, stamped steel oil pan, aluminum timing cover, harmonic damper, stamped valve covers, oil pressure verification report, and an installation instruction handbook.
