Can you help identify this Aluminum 427 engine?

HAHA poor washing machines,they the brunt of the mess when they live in a garage.I sell lots of stuff on ebay and almost all of it is photo'ed on or in front of the washing machine.I have seen many other adds with the same location.Most common is the orange or blue stains on the machine from soap spills.I guess its the only flat surface in most garages that doesnt have crap piled on it because the wife wont let it

BTW,thats a seriously nice piece you have there.Try and find the original home before you reinstall it.it could be worth a fourtune.
