You can make any block any size you want.
If you can not find it on the net or do not have access to EQ, the easiest way would be to pick up some graph paper and draw the actual block the size you want it be when it is finished - then cut out the individual pieces and redraw each piece and then add the 1/4 inch seam allowance all around the piece.
I think this is the block that you are talking about - This one is paperpieced. but it will give you another option of how to do it.
