S&S Evo Cam 510 (33-5124)

S&S - CAM FOR EVOLUTION-STYLE ENGINES

• 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.
• Made in the U.S.A.

510 CAM

• No spring spacing required.
• Works with stock pushrods, springs and hydraulic tappets.
• S&S' best bolt-in cam.
• Ideal for engines to 96" up to 10:1 compression.

520 CAM

• Makes best power in low to mid-range.
• Requires high-lift springs.
• Works with hydraulic tappets.
• Works well in all size motors up to 10:1 compression.

561 CAM

• Requires high-lift springs.
• For motors with up to 10:1 compression.
• Very good mid-range performance.
• Works with hydraulic tappets.

600 CAM

• Works well in large-displacement engines.
• 9.5 to 10.5:1 compression.
• Works with hydraulic or solid tappets.
• Makes best power in mid-range.
• Requires high-lift springs.

631 CAM

• Requires high-lift springs.
• Works with solid or hydraulic tappets.
• For all high-compression engines 11:1 and up compression.
• Makes best power from 4500 rpm and up.

640 CAM

• Requires high-lift springs.
• Designed for use with hydraulic tappets.
• Less overlap and fast ramps build higher cylinder pressure.
• Lower TDC lift makes installation easier.
• For large displacement engines (110"+) with 10.5 to 11.5:1 compression and smaller engines (96-107") with 11 to 12:1 compression.

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