I am looking at a new 2005 Silverado Crew Cab. Someone told me that the

5.3 in the Crew Cab only had been refined/redesigned/upgraded early in the model year. Does anybody know the facts behind this? Also, where does the VIN start with the new motor?

Thanks

From what I can see...it looks like the 5.3 in certain applications will come with either a cast iron block or aluminum block. They've already been running the all aluminum 5.3 in the Trailblazers. There are some other changes, but nothing major.
