well, one thing you may consider is the following...Johnny probably sees more short blocks in a day then most of us do in a year
so it there is anyone on here who i would trust to tell me if the crack you are seeing in your block would be an issue, it is him
secondly, why are you looking for a .030 over block AND taking the boy to machine shops?
seems to me, if the block is .030 over, the machining is done, BUT if you are going to a machine shop anyway, who cares what the bore is? (provided you can bore over still, of course)
if you really want him to do some research, why not pose the LA/magnum question to him?
(if i were starting over, i wouldnt go with an LA, but that is me)
