slap(a)hoe I am also talking to this guy about the block I am getting more and more hesitant.slap(a)hoe I am also talking to this guy about the block I am getting more and more hesitant the more I read. Thanks for posting about it I was just about to myself. I will be watching this very close.
4" bore LS1 Although I have never dry sleeved an LS1 block, and don't recommend doing so, it is technically possible to dry sleeve an LS1 to 4" bore if done correctly.
Without more details as to the sleeve material used in this block and the outside diameter of the sleeves and how they were installed, I can't give an opinion on whether the block would make a sound piece or not at 4" bore, much less 4.030".
If the internals are good, one could always take out the internals and put them into an LS2 block. Most LS2 blocks will go to 4.030" bore with the factory liners.
For your info, the factory LS1 blocks have a gray iron liner that is only .075" thick. That is the reason why .010" over is the limit on the stock liners.
