LS-6-Specific Higher
Lift Camshaft
As the intake air comes through the manifolds
in greater volume, it is important for the air to enter the
combustion chamber as quickly as possible to produce power.
The LS-6 engine has a camshaft that has higher lift lobes
than the LS-1, resulting in a 5 percent increase in airflow
through the cylinder chamber. |
LS-6-Exclusive
Cylinder-Head Design
At the heart and soul of the LS-6: unique
cylinder heads for better engine breathing. Larger ports than
those in the LS-1 engine also improve airflow by 10 percent.
Compression ratio is a healthy 10.5:1. |
LS-6-Mass Airflow Sensor
Design
The mass airflow sensor has been designed
for enhanced airflow, contributing to the horsepower increase
over the LS-1 engine. Greater air intake means greater power
output. |
LS-6-Positive
Crankcase Ventilation System
Because of the LS-6’s increased performance
capabilities, changes were made to the positive crankcase
ventilation (PCV) design to improve oil control during high-speed
conditions (compared with the LS-1 PCV system). |
LS-6-Specific Engine
Block
The all-aluminum LS-6 engine block has been
refined to enable higher piston speed and higher overall rpm
than the Corvette LS-1 block on which it is based. Hollow-stem
intake valves and liquid alloy exhaust valves are lightweight
and designed to maintain solid contact with the rocker arms
during high-speed operation. |
LS-6-Specific
Engine Beauty Covers
Vehicle owners are always being asked, “What’s
under the hood?” With its red beauty covers, the LS-6 is as
impressive with its hood up as it is on the open road. (Sold
Separately) |
LS-6-Fuel Economy
Fuel economy is impressive: In the Z06 it
gets an estimated MPG 19 city, 28 highway* with the standard
six-speed manual transmission on the Z06. This will vary depending
on the vehicle it is installed in and your driving conditions.
*Note: Based on GM testing. Official EPA numbers not yet available. |
