CHEVROLET Silverado 1500 - Manual (Page 18)

THE POWER OF CHOICE.
There’s lots of news under the hood of
Silverado for 2006. The new 345 hp
VortecMAX V8, the 360 hp Duramax
6600 Diesel V8 and the 310 hp High
Output Vortec 5300 V8 lead the way. But
what really separates Silverado’s engine
lineup isn’t only the incredible output of
these engines, it’s also the range. Ten
different engines. Built for a wide range
of different applications, including towing,
with capacities ranging up to 7575 kg
(16,700 lb.).* Power alone is not the goal –
it’s finding the right characteristics to
meet the specific demands of a given
truck and the way you use it. Fortunately,
with Silverado, that choice is left up to you.
*For 3500 4x4 Regular Cab dual rear-wheel models
equipped with a fifth wheel hitch. Refer to the Trailering
with Chevy Trucks brochure for more information.

FEATURES OF THE VortecMAX
6.0L V8 ENGINE:
1 High-flow ports and combustion
chambers in the cast aluminum
cylinder heads help the
VortecMAX generate 345 hp.
A low-friction roller-rocker
valvetrain is also included.
2 The lightweight thermoplastic
intake manifold helps keep the
air intake cool. The runners use
smooth interior passages to direct
high-speed airflow to each cylinder.
3 Quiet operation and reduced
maintenance are the result of the
internally balanced high-strength,
cast iron crankshaft, which
employs undercut and rolled fillets
to reduce stress loads.
4 An ignition coil is provided for each
of the eight cylinders. Its precise,
high-energy spark helps increase
efficiency and reduce emissions.
5 Driver input is relayed through the
drive-by-wire Electronic Throttle
Control (ETC) that’s continuously
monitored by the PCM to match
power delivery with the transmission
shift schedule. As a result, the
transmission never has to search
for the correct gear, translating into
better performance and efficiency.

Silverado’s Tow/Haul mode isn’t
the overdrive lock-out function
you’ll find on some pickups.
With the touch of a button, the
Tow/Haul mode greatly enhances
Silverado’s hauling and trailering
capabilities, by producing a
more aggressive automatic
transmission shift pattern.
