A Design Study in Aluminum Castings
- GM Cylinder Block
Engine
Design
The
inline design is applicable to 6, 5, and 4 cylinder (4.2, 3.5 and 2.8
Liter displacement)engine configurations.
The
SUVs come equipped with the six cylinder version and the mid-size trucks
are equipped with the four or five cylinder versions of the engine
family.
All
three inline engines use the Vortec cylinder design and have a 93mm
bore x 102mm stroke with a double overhead cam using 4 valves per
cylinder.
The engines operate with a 10:1 compression ratio, but still
use regular unleaded fuel (87 RON).
The
three inline engines have 75% part commonality.
