sounds good breeze except static comp of 6.8 would be meh to drive on the street. agree about sleevse cracking, more often than not tho, that cracking isnt just tune, its also the fact of cylinder pressure, and sleeves walking under boost...

for high NA MRJDM, u need displacement and rpm to get real power, if thats the case might aswell sleeve it man. Adrian makes a mean sleeved block.

Weq, for an engine, stay in australia man, overseas ur going to get into trouble especially with high shipping costs.
