SBM engines are... rare and not worth it. Might have better luck with the APE BB engine. Though, something that old might not even exist anymore. What's wrong with your current one?

Does APE, Wiseco or JE have the pistons you need? My SBM engine used either JE or Wiseco. Can't remember. The cylinders were a custom order and only had cooling on one side of the block due to how large the cylinders were. If the big bore isn't over the safe threshold, you could have the existing cylinders bored out to use the BB pistons.
