LS Block Bore Size
 
Do any of you have experience in boring the 6.0/6.2 GM blocks? What is the maximum bore size for an NA application? Can a 4.065” LS3 block go .060” to 4.125”, or the iron block out .125” to 4.125”? The only info I can find online is from the boost group that seems to rarely go more than .005-.010 over. Anyone have any first hand experience with doing this?
