S&S 640 Cam For Harley Big Twin Evo

Features

For large displacement motors with compression ratios of 10.5-11.5:1
Can be used in smaller motors with 11:1-12:1 compression ratio
The S&S 640 cam features the latest design in controlled ramps and is intended for hydraulic lifters
With lower TDC lifts and faster ramps than the S&S 631 cam, the 640 cam builds higher cylinder pressure
Therefore it does not require as much compression as the 631
