VEGE DCTV 7.0L 427ci High Performance Long Block Remanufactured Crate Engine

Description

Regain authentic big block strip acceleration with the VEGE DCTV Remanufactured Crate Engine high-performance long block package. Displacing 7.0L across 427ci in a big block V8 format, this motor outputs 425 BHP at 5600 RPM and 460 lb-ft torque at 4000 RPM. Engineered for performance builds, it repowers sports coupes with relentless crankshaft power.

A four-bolt main cast iron big block engine casting features precision decked surfaces with a 4.25-inch cylinder bore and 3.766-inch stroke. The rotating group incorporates a forged steel crankshaft, forged connecting rods, and high-compression hypereutectic aluminum alloy pistons. Cylinder pressure achieves an 11.0:1 compression ratio for high-performance combustion. A 5.0-quart steel wet sump oil pan maintains continuous oil pickup. Total dressed dry weight registers 640 lbs for solid traction.

Key Features of VEGE DCTV

Performance restomod builders buy VEGE DCTV crate engine packages to recondition vintage sports cars and heavy muscle trucks without custom machine shop delays. Each remanufactured unit receives blueprinted bearing clearances, multi-angle valve seat profiling, and upgraded multi-layer steel head gaskets for sustained high-RPM operation.

• 4.25-inch cylinder bores feature diamond plateau honing to seat piston rings fast.
• High-performance camshaft grinds expand intake and exhaust air volume across upper RPM bands.
• 55.6mm intake valves and 47.7mm exhaust valves promote smooth combustion chamber scavenging.
• 106cc combustion chambers optimize flame propagation when utilizing premium pump fuel.
• Multi-layer steel head gaskets seal combustion fire rings under high thermal loads.
• High-rate valve springs inside the VEGE DCTV valvetrain eliminate valve float at high engine speeds.
• Four-bolt main bearing caps anchor the forged crankshaft under intense acceleration loads.
• Stamped steel rear-sump oil pan clears passenger car crossmembers and steering linkages.

Combustion Dynamics Dyno Output Specs

The power curve delivers massive big block torque between 1,500 and 6,000 RPM. Peak dynamometer output reaches 425 brake horsepower at 5,600 RPM alongside 460 lb-ft torque at 4,000 RPM. Camshaft duration measures 224 degrees on intake and 230 degrees on exhaust at 0.050-inch lift, alongside 0.520-inch valve lift. The motor runs on 93-octane premium pump unleaded gasoline. Intake manifold vacuum pulls 16 in-Hg at an 850 RPM idle. Operating oil pressure regulates between 45 and 70 PSI at 3,000 RPM.

Drivetrain Interface Engine Bay Clearance

The rear bellhousing pattern aligns flush to longitudinal four-speed manual and heavy automatic sports transmissions. An internal neutral balance crank flange connects straight to production flexplates or flywheels. Standard big block motor mount pads align with chassis rubber isolators, preserving three inches of clearance above the front crossmember and steering arm.

Break-In Protocol Maintenance Parameters

Pre-lube all engine oil passages with a pressurized tank before initial startup to protect journal bearings. Fill the crankcase with SAE 10W-30 high-zinc mineral break-in oil and bleed trapped air bubbles from heating circuit hoses. This high-performance big block motor is not engineered for turbocharging exceeding 8 PSI boost, competitive drag strip passes, or unmetered nitrous oxide injection.

• Run motor at 2,000 RPM for 20 minutes to bed in camshaft lobes.
• Drain initial break-in oil and install a fresh oil filter after the first 500 miles.
• Replace crankcase motor oil and inspect drive belts every 3,000 miles during regular service.

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.
