VEGE DO15 5.0L 307ci Car Truck Long Block Remanufactured Crate Engine

Description

Restore factory full-size vehicle acceleration using the VEGE DO15 Remanufactured Crate Engine 5.0L 307ci long block package. Generating 140 horsepower at 3,200 RPM and 255 lb-ft torque at 2,000 RPM, this classic pushrod V8 provides smooth, reliable propulsion. Precision line-bored main bearing saddles reestablish proper oil film clearance, ensuring whisper-quiet highway cruising across executive town cars.

Solid cast iron small-block casting employs two-bolt main caps clamping a micro-ground nodular cast iron crankshaft. Forged steel connecting rods hold hypereutectic aluminum pistons traveling within a 3.800-inch bore and 3.385-inch stroke. Compression measures 8.0:1 for detonation-free regular gas operation. The front-sump stamped steel oil pan holds 5.0 quarts, with dry weight at 470 lbs.

Key Features of VEGE DO15

Full-size wagon and sedan restorers buy VEGE DO15 crate engine units to revive classic station wagons, rear-wheel-drive sedans, and light trucks. Precision remanufacturing restores strict factory clearances, reducing mechanical downtime and cutting fuel costs across high-mileage road transport platforms.

• Hydraulic roller lifters track smooth camshaft lobes to reduce valvetrain parasitic drag.
• 44 mm intake valves flow broad air volume into combustion chambers to generate low-end torque.
• DO15 car truck packages receive precision plateau cylinder honing for immediate ring seating.
• Computerized dynamic balancing limits rotational vibration across the entire engine speed band.
• Multi-layer steel cylinder head gaskets provide positive combustion containment under thermal stress.
• Line-bored cam tunnels reestablish tight hydrodynamic oil wedge films during hot idle periods.
• Pre-hung double-roller timing sets maintain precise camshaft phasing without timing chain stretch.

Combustion Chamber Dyno Characteristics

Covering an operational RPM spectrum from 800 to 4,200 RPM, this V8 creates 140 peak brake horsepower at 3,200 RPM alongside 255 lb-ft torque at 2,000 RPM. Camshaft duration checks in at 180 degrees intake at 0.050-inch lift, with 0.380-inch valve lift. Standard 87-octane pump gasoline provides knock-free operation. Warm idle vacuum pulls 19 in-Hg at 600 RPM, with oil pressure steady between 35 to 55 PSI hot.

Chassis Clearance Transaxle Integration

The rear engine flange matches standard GM corporate bellhousing bolt patterns for TH200-4R, TH350, and 700R4 transmissions. External balance requires matching weighted flexplates or flywheels. Sump contours drop cleanly around steering linkages and suspension crossmembers, providing ample space around steering shafts, exhaust headers, and starter motor housings.

Maintenance Protocols Operating Boundaries

Rotate the oil pump drive gear using a priming shaft tool to circulate oil before turning the starter motor. Fill the crankcase with 10W-30 motor oil containing zinc anti-wear additives and burp all cooling air pockets. This long block is not engineered for aftermarket superchargers over 6 PSI or transbrake drag racing.

• Drain break-in motor oil and spin on a fresh filter after the first 50 miles.
• Change the crankcase oil and inspect serpentine belt wear every 3,000 miles of operation.
• Flush radiator coolant and test heater core lines every 12 months for thermal protection.

Factory Warranty Crate Contents

Backed by a 36-Month / 100,000-Mile nationwide limited warranty against remanufacturing defects. The secure crate contains the remanufactured long block, complete oil pan, front timing cover, reconditioned cylinder heads, pushrods, balance documentation sheet, and a comprehensive installation instruction guide.
