Help Identify This 340

thanks for all the info guys...i knew you could help me out...i was under the impression it was a '69 block myself, i just wanted to know that it was a block worth working with.

Now time to hyjack my own thread..lol

The story i've heard in reguards to this engine is that in the 90's it was in a dart running high 10's - low 11's....i realize that without knowing the cam and pistion it would be almost impossible to verify, but from the pictures of the heads, is there any clues to the internals? the engine did have a 850 cfm carb on it if that would help at all.

ALSO, i'm under the assumption the entire engine needs rebuilt, and I'm not wanting to spend 3 or 4 grand right now to do so. So would i be better off sticking the engine in the corner and running the engine i already have in my car (318 w/ mild cam and edlebrock preformance intake, long tube headers) or putting new bearings in the 340 and giving her a shot? or a combo of stealing parts from one for the other...
