Why don't you grind or drill out the ends of the crack and have that cylinder sleeved, as that would be cheaper than buying a block?

I've been running one sleeve in a SD block,+.030. Block has over 200 runs in stock configuration though.

Default Just Asking

ponchorob,

Will your pistons work in a standard bore 455? Might give you more options to choose from in your search.

Do you have connections in the US to inspect and arrange shipping?
