VEGE Remanufactured DFA5 4.9L 300ci Heavy Duty Long Block Engine

Description

Confronting stripped intake manifold threads? Select the VEGE DFA5 Long Block Engine to execute a dependable commercial long block repower on hard working Ford utility trucks. This 4.9L 300 cid Inline-6 produces 145HP at 3,400 RPM. Technicians must check exhaust manifold heat riser valve operation before intake and exhaust manifold combo installation.

Solid ASTM A48 Class 35 cast iron forms the rigid 6-cylinder inline block case. A forged steel crankshaft pairs with forged steel connecting rods inside this VEGE engine core. Starter draw measures 165A on 12V vehicle circuits. Dry weight measures 515 lbs with an unrigged stance of 34in length by 21in width by 28in height. Sump holds 6.0 quarts.

Key Features of VEGE DFA5

Auto repair facilities buy VEGE DFA5 Long Block Engine packages to avoid machine shop queues during an industrial engine rebuild project. New valve seats and bronze valve guides guarantee true valve seating across thousands of operating hours.

• Cast iron cylinder heads feature optimized port contours to produce broad low end torque.
• Direct gear driven camshaft design eliminates timing chain stretch across severe fleet usage.
• Hypereutectic aluminum pistons resist thermal ring pinching inside diamond honed cylinder walls.
• The DFA5 commercial core maintains 0.0016in rod bearing oil clearances under heavy dynamometer loads.
• Seven main bearing caps lock the rotating assembly into the rigid bottom end cradle.
• High volume oil pumps supply constant pressurized lubrication to internal oil galleries.
• Multi layer steel head gaskets clamp down to eliminate combustion bore leakage.

Dynamometer Bench Performance Output Metrics

Dyno validation charts indicate 145HP at 3,400 RPM alongside 265 ft-lbs torque at 2,000 RPM for this DFA5 long block engine. Pressure transducers indicate 52 PSI oil gallery pressure at 2,000 RPM with oil sump temperature held at 195°F. Compression testing demonstrates 170 PSI per cylinder with variance under 4%. Crankshaft dial indicators verify 0.0002in TIR total runout. Exhaust manifolds record steady 1,180°F temperatures during full load testing.

Field Installation Preventative Maintenance Directives

Manual throttle cable linkages require 4 lbs pull force to sweep from idle stop to wide open throttle. Installers must avoid this heavy duty replacement engine for vehicle chassis lacking length clearance for 34in inline 6 engine blocks or vehicles running blocked radiator cores.

• Discard break in oil after 500 miles or 30 hours then fill with 10W-30 motor oil.
• Inspect cam gear backlash clearance before installing the stamped steel timing cover.
• Torque cylinder head fasteners in proper sequence up to 85 ft-lbs following initial thermal break in.

Crate Manifest Factory Warranty Overview

Backed by the VEGE build standard, this package features a 3-Year or 100,000-mile warranty. The rugged wooden shipping crate holds the long block core, oil pan, front timing cover, valve cover, oil pump pickup, plus factory signed dynamometer test sheets.
