Need Junk 440 Short Block

I just need a junk 440 big block. Can be cracked, rusted or whatever.
I'm putting a big block in my Dart and I would like to have a 440 (while my 440 is being built) to use as a template so I can try to fit everything in the engine compartment while I wait for my real engine.
I'm located in western New York.
Thanks.
