EcoTec3 Engines Overview

[Bowtie2Sierra]

If I could find a clean, low mileage, and completely stock 05-06, that is what I would love to have. Still my favorite.

I agree. 05-07 Classic Silverado 2500HD would be my choice!

Idk who to blame. If you can afford a $60k truck you probably don't care about the improved mileage of the 5.3 over the 6.2.

Big Gov't cares about that for you
