S&S Cycle 600 Cam - Evolution

600 CAM EVO BIG TWIN S&S camshafts and other related valve train parts go through extensive dyno testing and usage on the track and street

Since many S&S cams are high lift types, they are available with a cam only or in a kit with a set of the appropriate S&S high-performance valve springs

Made in USA

508 Cam:

Bolt-in cam intended for stock engines with less than 10:1 compression ratio

Quiet valvetrain with excellent low/mid range torque for touring and 2-up riding

510 Cam:

For engines up to 93 with no greater than 10:1 compression

Bolts-in and works with stock or ported heads - about a 10 horsepower gain over stock

Horsepower gains similar to S&S 502 cam but better low- and mid-range torque

Improved ramp design for quieter operation

Valve spring spacing not required

Other normal clearance checks recommended

520 Cam:

A replacement part for S&S emissions certified engines

Short duration emissions cam with very little overlap to reduce emissions of unburned hydrocarbons

Requires high lift springs and normal clearance checks

1000-4500rpm (80-96)

561 Cam:

Works in all displacement Big Twin V2 with a variety of compression ratios

Ideally suited for stock to 88 engines with up to 11:1 compression, 96 engines with 10:1 and 98 engines and larger with no greater than 9

5 to 1 compression

Moderate duration makes for great mid-range performance

Requires high-lift springs and normal clearance checks

585 Cam:

A versatile cam for engines with up to 10

5:1 compression ratio

For 80 to 96 engines with 10:1-10

5:1 compression and larger engines with 9

5:1-10:1 compression ratios

Provides a streetable combination of low end torque and top end horsepower

This cam is used in the S&S 111 Super Sidewinder Plus engines

Requires high-lift springs and normal clearance checks

600 Cam:

Originally designed for the legendary S&S 40th Anniversary Engine

The S&S 600 cam has proven to be an exceptional cam in any large displacement engine with 9

5:1 to 10

5:1 compression and is the cam supplied in the 4-1/8 bore 117 Super Sidewinder Plus engine

Good power across the RPM range

Requires high-lift springs and normal clearance checks

640 Cam:

For large displacement motors with compression ratios of 10

5-11

5:1 or smaller motors with 11:1-12:1 compression ratio

Does not require as much compression as the 631 and provides a more linear power delivery

3,000-6,000rpm
