I've heard from multiple sources that late-model LS1's (01+, or maybe 02+) use the LS6 block. If that's true, I'm guessing new LS1 crate engines also use the LS6 block. So basically it comes down to what heads/cam are installed. Look at the front corner of the cylinder heads. If '241' is stamped there, then they're LS1 heads; if '243' is stamped, then they're LS6 heads.
