Beskrivning av S&S 640 CAM 84-99 EVO

640 Cam

S&S Cams are tested on the dyno, street and track before being offered to the public

With hundreds of hours of testing on each cam, you know you are getting the best cam S&S can produce

For large displacement engines (110"+) with 10.5 to 11.5:1 compression and smaller engines (96-107") with 11 to 12:1 compression

Requires high-lift springs

Less overlap and fast ramps build higher cylinder pressure

Lower TDC lift makes installation easier

Designed for use with hydraulic tappets

Installer must check coil bind, valve-to-valve clearance, valve-to-piston clearance and cam lobe to case clearance.

Made in the U.S.A.
