Donovan is no longer offering the D block for sale as far as I'm aware. The block will accept any Model A/B flathead or Overhead valve head made for an A or B block as the cylinder spacing and head bolt layout is the same as a Ford block. Donovan blocks do come up for sale on occasion, but not very often.
