VEGE VFR7WCA 6.4L 391ci Heavy Duty Long Block Remanufactured Crate Engine

Description

Engineered with deep-skirt FT iron castings, the VEGE VFR7WCA Remanufactured Crate Engine in 6.4L 391ci heavy duty long block trim produces brute working power. This remanufactured Ford FT commercial V8 outputs 235 brake horsepower at 4,000 RPM and 370 lb-ft torque at 2,000 RPM. Built for medium-duty commercial trucks, this unit drops straight into heavy industrial engine compartments.

Extra-thick FT series cast iron engine blocks feature deep skirts extending below crankshaft centerlines and torque plate honed 3.780-inch bores. A heavy remanufactured forged steel crankshaft spins with a 3.784-inch stroke on four-bolt ductile iron main caps. Heavy-duty forged steel connecting rods attach to full-skirt hypereutectic aluminum pistons. This engine features a 7.4:1 low compression ratio, 8.0-quart commercial oil pan, and weighs 650 lbs dry.

Key Features of VEGE VFR7WCA

Municipal fleet mechanics buy VEGE VFR7WCA crate engine packages to rebuild Ford F-600, F-700, and commercial dump truck chassis. Each long block undergoes CNC deck machining to maintain proper compression ratio balance and exhaust manifold gasket compression under sustained payload stress.

• Sodium-cooled exhaust valves and hard Stellite valve seats resist intense combustion heat under continuous wide-open throttle hauling.
• Forged steel crankshafts featuring massive 1.75-inch snouts support heavy front-mount auxiliary hydraulic pump drives.
• Four-bolt ductile iron main bearing caps secure the bottom end against severe commercial torque deflection.
• 3.780-inch bore cylinders feature four-ring piston architecture to control oil consumption and sustain high cylinder compression.
• 0.440-inch intake lift commercial flat tappet camshafts generate immense low-end torque starting right off idle speed.
• High-volume commercial oil pumps maintain constant lubrication across all rod, main, and distributor drive gears.
• Viton rear main crank seals guard against oil leakage at the commercial transmission bellhousing interface.
• VEGE VFR7WCA commercial packages include brass expansion plugs to resist severe cooling jacket corrosion.

Heavy Commercial Dyno Output Parameters

The heavy-duty commercial flat tappet camshaft features 200 degrees intake and 208 degrees exhaust duration at 0.050-inch valve lift with 112 degrees lobe separation. This industrial profile generates 19 in-Hg intake manifold vacuum at 600 RPM, maintaining strong power brake assist under full gross vehicle weight conditions. Generating 370 lb-ft peak torque at an ultra-low 2,000 RPM, this V8 operates clean on budget 87-octane pump gasoline. Calibrated internal lubrication ports sustain 45 to 65 PSI hot oil pressure under continuous commercial towing operations.

Chassis Clearance Bellhousing Mating Dimensions

The Ford FT commercial bellhousing pattern connects straight to Clark, New Process 435, and Allison automatic transmissions without adapter plates. Heavy commercial front and side motor mount pads drop flush onto factory medium-duty truck chassis crossmembers. The deep stamped steel rear sump pan clears straight front axle beams and steering drag links.

Break In Maintenance Schedules

Technicians must pre-lube internal oil galleys using an external priming tool before turning the starter motor cold. Fill the crankcase with SAE 15W-40 commercial motor oil along with high-zinc break-in lubricant to protect flat tappet camshaft lobes during initial operation. This engine is not designed for passenger car conversions, turbochargers, or competitive racing.

• Drain initial break-in motor oil and install a fresh oil filter after the first 500 miles.
• Service engine crankcase oil and spin-on filters every 3,000 miles during heavy commercial operations.
• Inspect distributor gear wear, governor drive seals, and cooling system hoses every 12 months.

Warranty Terms Manifest Breakdown

VEGE protects this heavy-duty commercial crate engine with a 36-Month or 100,000-Mile commercial powertrain limited warranty. The heavy wooden transport crate contains the assembled long block, stamped valve covers, front timing gear cover, oil pan, oil pump, balance certificate sheet, and technical installation guides for fast customer turnaround.
