I too was looking at the Dart block, my concern was that LT1 heads, or aftermarket LT1 heads really don't have the flow to feed a serious 427CI. To make a 427CI LT1 you would need to go the route of someone like N20Dave and look at SB2 heads. By the time you get the heads and aftermarket LT1 block it would be a whole lot cheaper to just go a different route. If you look at those single digit LT1s they too suffer some some of the problems inherent with stockblocks. Cap walk, block flex. an ultra strong block such as dart would built would allow you to push much further. If I ever decide to loose the LT1 it would be replaced with a big block.

Of course, UB isn't going to have that problem, he already has heads with major flow potential and a stud girdle. Unlike the rest of us, Bob has the uncommon parts that will allow him to push a stock block where the rest of us can't.
