No, some of the truck motors are all aluminum. I know when the 5.3 first came out the H.O. version was aluminum.

Exactly where do you get your info? This is the second post where you are completely off base.

The Vortec 5300, or LM7/LM4/L59/L33, is a V8 truck engine. It is a stroked (by 9 mm) version of the Vortec 4800 and replaced the 5700 L31. L59 denoted a flexible fuel version, while the LM7 was the standard version of the engine.

Power output is 285-295 hp (213-220 kW) and torque is 325-335 ft·lb (441-447 N·m). Displacement is 5.3 L (5328 cc) from 96.01 mm bore and 92.00 mm stroke. Vortec 5300s are built in St. Catharines, Ontario, Romulus, Michigan, and Silao, Mexico.

[edit] LM7

The LM7 Vortec 5300 was introduced in 1999, and can be considered the "garden variety" version of the Generation III 5.3 liter V8's.

LM7 applications:

* 2002-2005 Cadillac Escalade 2WD
* 2002-2006 Chevrolet Avalanche
* 2003-2007 Chevrolet Express/GMC Savana
* 1999-2007 Chevrolet Silverado 1500
* 1999-2007 GMC Sierra 1500
* 1999-2006 Chevrolet Suburban/GMC Yukon XL
* 1999-2006 Chevrolet Tahoe/GMC Yukon

[edit] LM4

The LM4 was an aluminum block version of the LM7, and had a short production life. It should not be confused with the L33.

LM4 applications:

* 2004 Chevrolet TrailBlazer EXT
* 2004 GMC Envoy XL
* 2004 Chevrolet SSR

[edit] L33

The L33 was an aluminum block version of the LM7, and was referred to as the Vortec 5300 HO in marketing materials. Horsepower increased by 15, to 310, over the LM7, and torque was unchanged. It was only available on extended cab 4WD pickup trucks.

L33 applications:

* 2005-2007 Chevrolet Silverado 1500 4WD
* 2005-2007 GMC Sierra 1500 4WD

wow THANKS ! i guess the L33 isn't something i'd find on every corner of the street so pricing might come close to a used 5.7 ls1 then ?

It really depends on if the owner actually knows what they have. Even though it is an aluminum block, I highly doubt the going price will rival that of the LS1.
