VEGE DFH3 7.0L 429ci Heavy Duty Long Block Remanufactured Crate Engine

Description

Turn high-stall torque converters with the VEGE DFH3 Remanufactured Crate Engine 7.0L 429ci long block package. Producing 210 horsepower at 4,000 RPM and 360 lb-ft torque at 2,600 RPM, this heavy-duty 385-series V8 provides massive low-end pulling muscle. Precision line-honed main saddles and remanufactured high-flow cylinder heads restore original combustion efficiency across vintage commercial trucks and industrial haulers.

Massive cast iron 90-degree block architecture utilizes two-bolt main bearing caps to clamp a balanced nodular cast iron crankshaft. Heavy-duty forged steel I-beam connecting rods anchor cast hypereutectic pistons across a 4.360-inch cylinder bore and 3.590-inch stroke. Compression ratio checks in at 8.5:1 for safe fuel operation. The stamped steel front-sump oil pan holds 6.0 quarts, with total dry weight at 630 lbs.

Key Features of VEGE DFH3

Choose to buy VEGE DFH3 crate engine packages to overhaul heavy commercial dump trucks, tow vehicles, and vintage motorhomes. Each remanufactured long block features resurfaced deck planes and precision-machined valve seats to ensure decades of dependable pulling service under heavy continuous cargo demands.

• Massive cylinder head intake ports deliver broad air charge volume into large-displacement cylinders under load.
• 52 mm intake valves optimize mixture fill rates to generate exceptional low-RPM pulling muscle.
• DFH3 heavy duty engines incorporate induction-hardened exhaust valve seats for unleaded fuel durability.
• Line-honed main bearing tunnels establish uniform hydrodynamic lubrication films under heavy engine loads.
• Plateau-honed cylinder sleeves provide prompt ring break-in without cylinder bore scuffing.
• Hydraulic flat-tappet lifters eliminate valvetrain noise without requiring periodic lash adjustments.
• Heavy-duty double-roller timing sets maintain precise camshaft timing under erratic equipment drag.

Combustion Chamber Dyno Characteristics

Operating across an engine band from 800 to 4,500 RPM, this big-block V8 outputs 210 peak brake horsepower at 4,000 RPM and 360 lb-ft torque at 2,600 RPM. Camshaft duration measures 194 degrees intake at 0.050-inch lift, with 0.440-inch valve lift. Designed to run on standard 87-octane pump gasoline. Manifold vacuum holds at 18 in-Hg at 600 RPM idle, backed by 40 to 65 PSI hot oil pressure.

Chassis Clearance Transaxle Integration

The rear block interface utilizes the classic Ford 385-series bellhousing bolt pattern for attachment to C6 automatic and heavy-duty four-speed manual transmissions. Internal neutral balance simplifies flywheel and clutch installation. The deep front-sump pan clears solid front axles, leaving abundant room for steering drag links, starter nose cones, and large exhaust manifolds.

Maintenance Protocols Operating Boundaries

Rotate the oil pump intermediate shaft with an external drill tool to prime the lubrication system before initial cranking. Fill the sump with 15W-40 heavy-duty oil containing high zinc levels and purge all cooling passages. This unit is not engineered for high-RPM drag racing, alcohol fuels, or multi-stage nitrous systems.

• Discard break-in motor oil and install a replacement oil filter after the first 50 miles.
• Conduct regular oil changes and check valve gear noise every 3,000 miles of equipment operation.
• Flush engine coolant and inspect radiator fins every 12 months for steady heat rejection.

Factory Warranty Crate Contents

Includes a 36-Month / 100,000-Mile commercial warranty covering remanufactured components and machining. Crate packaging contains the remanufactured long block, complete oil pan, reconditioned cylinder heads, pushrods, timing cover, balance verification report, and an instructional startup guide.
