In this example, your 1962 Ford Falcon straight-6 engine has a
published Engine Displacement of 169.95 CID. The spec Bore
and Stroke are 3 inches and 2.94 inches, respectively. Calcu-
late the exact cubic-inch displacement by going to a larger Bore
of 3.75. your calculator defaults to 8 cylinders, and since the
1962 Ford Falcon only has 6 cylinders, you will need to change
the number of Cylinders.

bore — Based on engine Displacement and Stroke
Building from one of the previous examples, you want to push
your cubic-inch displacement to a maximum of 405 CID to be
competitive at your local club races, as well as meet class engine
requirements. Recall that the stock Bore and Stroke on the 1968
Ram Air II engine is 4.12 and 3.75 inches, respectively. keeping
the stock Stroke length, calculate a new Bore size.
