If you know a few pieces of information, you can turn a Vortec 5.3L block into an LS mill making way over 500 hp and out-displacing an LS3! To prove it, we dyno one at Westech Performance.. Was going to throw the block but I know some 5.3L's can be bored to a 5.7L. Is this all 5.3's? I've got a mild cammed L33 in my car now but I had the thought of boring this block out and building a better motor for the future when the L33 either pops or I want more power. Boring any 5.3L to a 5.7L possible or is it only some of them?

I have a iron 5.3 and the legendary infamous LS1 5.7 status symbol keeps luring me to the dark side. I want a 5.7 to say I have a LS1 but the bores look really good, albeit a little rust around one of the top of the cylinders that should clean up with a hone. So, I know the 5.3's make decent power, but, since it is a used engine, is it worth spending the money for new pistons and getting it bored?. There is so very much poor information out there about taking a regular 5.3 truck engine and boring it .100 over to make it into a 5.7. I was hoping there was someone out there that had done it before and could answer a few questions about what parts would be required.
