what 3B sez .... you want a long block, and you should be able to find a complete used 283 advertised privately 'for rebuilding' or as a 'rebuildable core' - and if the rebuilder has a 283 on the shelf, it's likely they'd be happy to sell it with no core, they prolly don't get much call for them anymore
