The expert opinion available on this net would be appreciated.
I have a 681F6015 "virgin" block for sale on ebay right now. By virgin I mean that it has not been bored out and still has the 82.5 mm bore and a crankshaft that appears to be original and not re-ground. The caps appear to be exactly like the caps on a recent 701 block that sold on ebay a few days ago.
What I need to know, so that I can represent it correctly, is if these caps are the "square shouldered" or "round shouldered" I have had two different "expert opinions" one says they are definitely Square Shouldered and the other says they are definitly Round Shouldered - are there any referees out there?
Attached are the pictures. One is of the 701 caps from the ebay sale a few days ago and the rest are from my block now on ebay. I really want to properly represent the merchandise so you exediate help would be appreciated.
I am open to a phone call if that would help 931-205-0215

Square.
'Square' refers to the flat horizontal bottom face, and 'round' is when the bottom face is curved concentric to the crank (viewed end on). If you have the Robinshaw & Ross Elan book, see p.70 - a picture speaks a thousand words...
