By looking at the formulas for calculating those two values, it's obvious that they depend on each other:

**Piston Compression Height** = Block Length - (Stroke of Engine/2 + Rod Length) - Deck Clearance

Example: 9.245 - (3.622 / 2 + 6.098) - (-0.007) = 1.329

I couldn't reach the formula for calculating piston deck clearance but by looking at required parameters in the calculator on this link, it's obvious that the piston compression height is required to calculate piston deck clearance.

http://www.kb-silvolite.com/calc.php?action=deck **My question is:** is there a formula for calculating any of those two values without referring to the other one?

I have seen a calculator on this link but I don't think that I can reach some of the values they are asking for
