Reground cam prices are exchange. You will need to return a useable cam core.

Note: As a general guide, all of the cams listed, except race only, will give you about 10% increase in power over the stock unit. Care must be taken in selecting a cam that will give power where it is needed. For example, an autocross application needs power in low to mid-range, so a cam that doesn't start to produce power until 4500 rpm would not be the right choice for this application.
