what do you guys think? 
A hundred bucks is cheap if it's a complete engine, not cracked, standard bore and you believe you can clean it up with a
slight bore. On the other hand, FK engines (327cid/210hp) aren't rare or in high demand. I guess it comes down to, do you need (or want) another project for the summer? Now, if the engine assembly code had DZ at the end...

Either way, have fun and keep looking!
