Chevrolet 19432776 6.0L 364ci V8 Base Long Block Engine

Description

Variable cam timing phaser pin shear and oil pump relief valve sticking cause sudden pressure drop across heavy fleet haulers. The Chevrolet 19432776 6.0L 364ci V8 Base Long Block Engine eliminates valvetrain timing drift during commercial long block repower cycles. This 8-Cylinder 360HP platform requires camshaft position sensor clearance verification prior to torquing the front timing cover.

ASTM A48 Class 35 deep-skirt gray iron forms the cross-bolted six-bolt main block casting. A micro-polished nodular iron 3.622in stroke crankshaft drops into powdered metal connecting rods and hypereutectic aluminum pistons topped with A356-T6 rectangular-port heads. This Chevrolet engine core demands a 12V 175A starter draw during cold shop cranks. Dry weight measures 445 lbs within a 28in length, 26in width, 27in height stance holding 6.0 quarts of oil.

Key Features of Chevrolet 19432776

Fleet managers buy Chevrolet 19432776 Base Long Block Engine units to restore heavy chassis service routes. Every industrial engine rebuild integrates upgraded variable valve timing actuators and precision line-honed cam bearing tunnels.

• Cylinder bores measure 4.000in with diamond plateau hone surface finishes.
• Main bearing journal clearance holds at 0.0015in across all six-bolt main saddles.
• Hydraulic roller lifters prevent camshaft friction under sustained expressway hauling.
• Rectangular-port aluminum cylinder heads maximize high-RPM airflow efficiency.
• Multi layer steel head gaskets lock combustion pressures inside cylinders.
• This 19432776 commercial core features computer spin balancing within two grams.
• Stellite faced exhaust valves resist thermal fatigue under heavy trailer loads.

Dynamometer Test Station Data

Controlled brake cell testing verifies that this 19432776 long block engine produces 360 continuous BHP and 380 ft-lbs of torque at 4200 continuous load RPM. Main gallery oil pressure measures 56 PSI while oil sump temp levels at 194°F under full thermal loading. Exhaust gas temp tops at 1310°F along the exhaust manifold runner. Cylinder compression checks between 180 PSI and 188 PSI across all eight cylinders. Crankshaft center journal runout holds within 0.0003in TIR.

Chassis Placement Setup Boundaries

Electronic drive-by-wire accelerator pedal return sensors require 4 lbs of steady pedal resistance to ensure consistent return action. This Gen IV motor is not engineered for carbureted marine retrofits, dry-sump track cars, or aviation airframes.

• Evacuate initial break-in petroleum motor oil after 500 miles or 30 run hours.
• Verify non-adjustable roller rocker arm bolt torque at 22 ft-lbs on base circle.
• Torque cylinder head bolts in three stages to final angle specifications.

Commercial Protection Package Contents

Backed by the factory Chevrolet assembly standard, this base long block carries a 3-Year 100,000-mile parts warranty. The wood crate houses the assembled engine core, oil pan, front timing cover, valve covers, oil pickup tube, and signed dyno load sheet.
