I don't think .030 is possible. You can go .010 to .015 if I remember right.

i believe some have, its getting very very close at that point though.. you have to get it tested because it may not have enough wall thickness to, but at the same time it may.

ive read alot of threads on this so a search may be helpful, alot of people want to put ls7 heads on this block but they have a 4.1 min bore.

you could always sleeve it but then your cheap idea will be thrown out the window...

Talk to Texas Speed they have bored some to 4.100. The GM performance book says you can bore +.030. I am going to bore one to 4.070.
