I've heard a few people talk about doing this... Basically getting the smaller motor and boring it out, while still allowing there to be more meat on the cylinder walls.. And I think there's a shorter stroke allowing more revs, but I'm not sure..

I've been curious, has anyone on here done this setup? Are the stated benefits above correct?

what you would be getting is a iron 5.7. Stroke is the same between the 2. This would be a good idea for someone who wanted the strength of iron but wanted to keep the cubes stockish.

With the money in machine work your spending on boring the block that far.

I think it would be foolish to not just use a $300-$400 6.0L block and get the large bore size instead.

Also after they get done boring the 5.3 block out there is less material there then a 6.0l iron.

really? i did not know that. If you are using a small turbo....or limited in turbo size (think incons here) the smaLLER cubes will be better....say 346 vs 408 as the bigger cubes will choke on a smaller turbo

Don't waste your time, get a 6.0 block and be done with it.

I think he is talking about the aluminum 5.3 block. I have read that the aluminum 5.3 and newer 5.7 blocks have exactly the same sleeves and its no problem boring them to 5.7 size.

Thats what I remember reading anyhow. Crapload of 5.3 aluminum blocks were floating around a couple years ago cheap if I recall and thats why it was brought up.

You and another fella were the ones who got me thinking about the idea. I was just trying to clarify the reasons for it all.

I know about the turbos choking out on a large motor.. If I ever got my hands on an Incon kit, I'd definitely keep stock cubes, or even less...

Ah ok. Makes sense.... So I guess scratch that off the list of FI ideas.
