```
cc = ci * 16.3871
```
Where:
* cc is the displacement in cubic centimeters
* ci is the displacement in cubic inches
Therefore, the displacement of an 88 ci S&S motor in cc is:
```
cc = 88 ci * 16.3871 = 1,442.3098 cc
```
Rounded to the nearest whole number, the displacement of an 88 ci S&S motor is 1,442 cc.
