another thing you could try is downloading the Tapatalk app and turning on post notifications in the parts for sale section. that way if a block comes up you'll be notified immediately and have a better opportunity of snagging it before someone else does
I have a std 109 short block been hot tanked and checked by machine shop but I'm in Illinois by st.louis Mo. Std bore but in good shape. With good std. crank, rods, and pistons I would take $450 or $600 with a set of bare 445's that have been checked for cracks. Not really wanting to ship though.
