Chevrolet Performance 19209705 Crate Engine Assembly

Distributor housing cracking and poppet injector fuel dripping cause chronic misfires on hard-working utility pickups. The Chevrolet Performance 19209705 Crate Engine Assembly restores lost combustion power during this commercial long block repower. This 8-Cylinder 255HP Vortec engine requires distributor shaft gear engagement depth verification prior to tightening the hold-down clamp.

ASTM A48 Class 35 heavy cast iron forms the rigid four-bolt main cylinder block and Vortec cylinder heads. A nodular iron 3.480in stroke crankshaft spins within copper-lead tri-metal bearings inside line-honed main webs. This Chevrolet Performance engine core demands a 12V 170A starter draw during cold cranks. Dry weight is 435 lbs, spanning a 28in length, 25in width, 27in height envelope with 5.0 quarts oil capacity.

Field Installation Setup Guidelines

Throttle cable linkages need 5 lbs of pull force to maintain smooth throttle body blade movement without sticking. This factory truck crate engine is not engineered for high-RPM marine race boats, dry-sump track cars, or aviation airframes.

- Evacuate initial break-in petroleum motor oil after 500 miles or 30 run hours.
- Check hydraulic roller lifter preload at zero lash plus one quarter turn.
- Torque cylinder head bolts in three stages to 65 ft-lbs final specification.
