I am not a detective to prove anything. That is fact, Google it or read on corvette forums.
Ask any engine builder they will tell you the same about LS7 block being destroyed from detantion, and re-sleeved aluminum LS blocks having issues with cooling system. Besides the LS7 block all other LSx aluminum blocks are cast around the sleeves. Sleeves have to be machined out in order to press fit the new sleeves. During the process when new sleeves are pressed in the, block cracks (hairline cracks which can not been seen) around the water jackets near the sleeve(s) causes it to leak or pressurize the cooling system. If you are okay with that then go for it, just carry few extra gallons of coolant to add in during fuel stops.
By any chance have you worked on or assembled re sleeved none LS7 aluminum block?
