Instructions: Enter a value in the un-shaded boxes below as they pertain to your engine.
Note: For pistons BELOW the block @ TDC – value in box must be a POSITIVE number (.000)
Note: For pistons ABOVE the block @ TDC – value in box must be a NEGATIVE number (-.000)
Note: For a DISH piston – value in box must be a POSITIVE number (0.0)
Note: For a DOME piston – value in box must be a NEGATIVE number (-0.0)
Note: Manipulate the DOME/DISH & PISTON to DECK volumes to get the ratio you want.
