I have had 3 or 4 LS builds now, so I know the quirks.

I made ~300whp for about 28,000 miles (this was all you internals, but a stock 81mm bore). Went back and retuned for more and within 1000 miles I had cracked a sleeve. Rebuilt, cracked another sleeve at about 355whp...sooo...do with it what you will.
hmm thats pretty crazy man
i talked to jenson and he said he thought that the injectors and the head will be the limiting factors.
but thats sucks i've never heard of people cracking ls sleeves like that.
