Cracked Block - How bad is too bad?

[A12pilot]

So, the original block to the 68 Mustang has two cylinders with cracks in them. One is really bad, and the other isn't as bad, but they're both bad. I think that made sense... [img]<<GRAEMLIN_URL>>/hmmm.gif[/img] I'm unfamiliar with repairing engines as far as how bad a crack can be before the block is deemed unblockable [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img] I'll post up some pics later, but after talking with a few guys, seems almost anything short of missing pieces can be fixed. Is this true or not true? Being the original block, I'd love to save it (obviously) but in standby is a correctly date coded engine from another 68 390 GT Mustang waiting just in case.

So, how bad does it have to be before it's not repairable? I don't mind shipping it out to have this done if anyone knows a shop that really specializes in this type of stuff. What's the worst you've seen that was fixed?

Thanks guys! [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]
