New Dart 4 bolt main, 9.5" deck, 4.125 bore, I believe it has Cleveland size mains. $1900 starting bid with no bids 2 days into a 7 day listing.
Put a 4.0" stroker in this and have a 427 SBF or take the bore to the max and have a 440. Think that would make enough HP for you?? :-) I'm making no statement about the price, nor do I know anything about this particular block, but if you want the absolute max in a SBF, this is the way to start.
