I certainly was keen to build my engine using one of their blocks, but how long can one wait...

 I talked with Dave about this when I stopped in for a tour while I was in the area in August.  He said that Kirkham originally had set up a deal with Darton, but then the CEO of Darton decided that the deal was not in his interest at a later point.  However David has a different cylinder liner idea based on a Bristol engine design.  The current problem is that they are just too busy at this point with other work to do the redesign work on the block.
Also while I was they were machining an aluminum block for Shelby, so presumably Shelby delivered at least one block this year.
