how to find a 340?

I don't know if this belongs here. my question is how do you tell a 340 from any other SB mopar motor. what gives it away? i only ask because i am looking for a 340 motor for my '69 valiant and i have a local junkyard that has plenty of mopars in its yard. i am going to go out there this weekend and take a look around but i need to at least have an idea of what to look at... also, can anybody lead me in the right direction as far as what these motors came in? any help would be greatly appreciated. that is why i am asking you guys on this great site for some info. Thanks.
