Picking Up 340 Short Block - What to Look For?

Hi All,
We came across a great deal we felt we should jump on. It is a 340 short block standard bore. The current installed engine in are 1970 Dart Swinger is a 340 bored 60 over and we worry it is just a matter of time before it gives out. But it has all the goodies on it.
For those who know the numbers here they are:
2780930-340-3
7*11*69
0B21294

I read the witchcraft numbers to mean the third casting from the mold. original casting made in 1969. 0 to mean a 1970 vehicle it came from followed by some of the vin numbers.
See the uploaded photos. I would appreciate any and all comments. The seller is going to measure on the spot the boring numbers with proper tools.


as advertised: "1969 / 1970 dodge block 340 cleaned and magnefluxed date 7 / 69 stn bore"

$678 us dollars.
