Simple but yet I feel dumb asking.........grr.........ok here goes.Is the A6 and Z6 BLOCK the same animal?
I know the heads are different but are the blocks the same thing?

 

Both use the same crank, and are to the eye visually the same. I honestly dont think their is a differnce, but I could be wrong. The Z6 also does not have a oil oriface jet on the face of the deck, but the a6 can come right out.
