Deck Clearance *
*Note: The output produced by this calculator refers to the piston being above or below deck. Remember that above deck subtracts from chamber volume, and a piston below deck adds to chamber volume, therefore the positive or negative value must be reversed when this number is used to calculate compression ratio.
