How to calculate deck height?

How to calculate deck height?

The simple math calls for dividing the stroke in half (3.48 / 2 = 1.74 inches) and then adding the connecting rod length and compression height. This is then subtracted from the engine’s deck height to find the deck clearance, which can be positive (above deck) or negative (below deck).

How to calculate piston deck height?

First, divide the stroke by two and add that to the rod length: 3.75 / 2 = 1.875, and 1.875 + 6.00 = 7.875. Next, subtract that answer from the deck height: 9.00 7.875 = 1.125. So the answer is that the piston compression height should be 1.125 inches.
