Thanks guys. To answer the first question, right now I would just like to put it together and run 12.99. More for later of course.
As for the cast crank 340 not being worth as much as I think... I don't expect to retire off of it. I'm not looking for a mint. Actually with a longer stroke, I would maybe think of using the 340 block for the bore advantage. But I'm thinking stock stroke, as fast as I can go without emptying my retirement account.
