Short block LO206

Don't know if this post is in the right spot but just have a general question to see if anybody does it will be my first you racing this coming May might have to run the lo206 doc that's the only class that they run at the track and I'll be running at does anybody have a used 206 stock motor that's for sale or just the block and I can always find us find a head somewhere for it but it's got to be sealed. If someone can help at all it would be great
