First off thanks for all the replies guys beer. So I see what I was thinking as it being a 440-3 because of that casting number on the side of the block is completely wrong. Differences in the blocks some say no, some say yes, most say difference in heads and thermostat. I knew that the 413 industrial engine was a complete different animal. So I believe I am going to continue to look for a complete 440 engine out of a motor home, that way I know that is what I have and it will work. Not going to get hung up on that casting number on the side. Hopefully I'll find one that hasn't been laying out in the weather and seized this time.
Thanks
