looking at an 06 sierra. got ???

[crepitus]

i pretty much have my mind set on the 06 1500 extended cab 4x4. the thing i dont know about is which motor to go with, the 4800 or the 5300. is that power that much different? what about the mpg? i dont do any towing really but do like power. is the 5300 that much worse in the gas mileage area? any other options i should look at or stay away from?

In that truck there won't be hardly any difference in mileage. The way I see it you'll never regret having bought the bigger engine.

remember if you get a 1500 4x4 Ext.Cab Standard Box with the Z71 on it you can get the 5300H.O. and that motor is a beast

 

I have it in my 06 and i chew up my friends hemi in it.

 

It is really leaps and bounds better than the iron block 5.3

Get the bigger motor. The bigger motor will get the same (or even better with a load) mileage, resale will be higher, and when you need it, you've got it.

You can justify going with the 4.8 liter if you select the LS model. They also come with basic equipment, such as cruise, tilt, power windows and locks, and content theft alarm. And are priced about $ 3K less than a base LT1 model. You cannot get the Z71 package with the LS model. But if you are looking for the best value for your dollar, the LS version is the way to go.

 

Just about all LT models will come with a 5.3 liter, because dealers (practically without exception) order the light duty power package on these trucks. This consists of the 5.3 engine, trailer tow package, and locking rear differential.

 

I looked at hundreds of new '06 4X4 pickups on the gm.com website, and I did not find any LT truck with the 4.8 liter engine.

do they all have the aluminuim 5.3 now?

[pm26]

No. Most of 5.3 engines on '06 trucks are still cast iron blocks. The aluminum block 5.3 is designeated as "High Output" version, , but the horsepower difference is pretty small - only about 20 HP more.

Get the new Vortec package...345 hp!

the aluminum block may only be 20 more horses but my god is it a beast
