1933 Oldsmobile Straight 8 engine help urgently needed!

[Guest 29nostchev]

I work in a restoration shop and we currently have an 1933 Oldsmobile Convertible Coupe Straight 8 car we are working on. We got the run around from the engine builder for 10 months and then finally get the engine back and the block is bad due to cracking. So we are in urgent need of either a block or complete engine. Also any information on what all years will fit this car or any other models across the general motors line up we could get an engine from. It is an 1933 Olds straight 8 240.33 cu in. Thank you very much for any information.
