I just think between building Kirkham Coupes and Cobras and taking on the Shelby orders, they're just too busy for a alloy block. They do make billet aluminum Girling calipers now.

 Patent issues with (darton?) cylinder sleeves? I'm NOT across it, just rumours and whispers. Others are better placed to advise. 
 
I certainly was keen to build my engine using one of their blocks, but how long can one wait...
