Another pathetic question: 5.3 vs 5.7
I've ran across plenty of LS engine blocks that are 5.3L but they say can become 5.7L. Is it an aluminum block that can be bored out to 5.7L? Or are we talking stroking it to 5.7L. Also, a truck 6.0L is the engine physicall bigger or is it bored out more?

As to why they make a 5.3, I have no idea. It must save GM money in the long run, but I can't imagine it saving that much. But, if you save $1 on each vehicle of a 40,000 vehicle run, it'll make a nice bonus gift for an executive -- like having their office bathroom remodeled or something.
