.490" valve lift. The low compression version of the Andrews B cam. High lift combined with short duration will improve performance on low compression engines (8:1 C.R. or less).
.490" valve lift. The low compression version of the Andrews B cam. High lift combined with short duration will improve performance on low compression engines (8:1 C.R. or less). Note: For 81-82 models. The height of original stock H-D valve guides restricts spring travel (and valve lift) to .430" or lower.
SILNIK
540" valve lift for Panhead; .514" valve lift for Shovel. For 84" to 93" strokers with no greater than 9:1 CR. Best gains occur in the mid range from 2500 to 5000 rpm where most riding is done. Relatively quiet and easier on the valve train than most other cams with lifts as high. Solid lifters or aftermarket hydraulic tappets are recommended; valve spring spacing and other normal clearancing checks required. 2500-5000 RPM.

.520" valve lift. Up to 96" engine with 8.5 to 10:1 CR. Short duration & overlap reduce emissions of unburned carbohydrates and makes good low and mid-range power. Good for dressers and riding double. Used in many emission compliant engines. Requires high-lift springs and normal clearance checks. 1000-4500 RPM.
Best cam for 4" bore engines with 9.5 to 10.5:1 CR. Originally designed for the limited S&S 110" Anniversary engine. Good power across the 3500-6000 RPM range.
.640" valve lift. Big inch engines with 10.5/11.5:1 CR. Smaller engines with 11:1 to 12:1 CR. With lower TDC lifts; faster ramps and shorter duration it builds higher cyl. pressure and requires less CR and offers a more linear power delivery as the 631. Supplied with the S&S 124" SSW+ engines. 3000-6000 RPM.
.630" valve lift. For high RPM street/race applications with 11:1 and higher compression ratios. Great performance cam but hard on valve train components. Can also be used with solid lifters. Valve spring spacing and other normal clearancing checks required. 4500-6500 rpm.
.585" valve lift. For 80" to 96" engines 10:1 to 10.5:1 CR. Larger engines with 9.5:1 to 10:1 CR. Provides streetable combination of low end torque and top end horsepower. 3500-6000 RPM.
.510" valve lift. Bolt-in cam for 80" (1340cc) to 93" engines with stock or ported heads. Up to 10:1 CR. With a stock engine; aftermarket slip-on mufflers and a Super E carb a 10HP power gain was realized at 5500 RPM.
.495" valve lift. Bolt-in. Similar to EV3 but with faster open and close ramps and longer duration. Increased static compression for improved top end 6000+ RPM performance with stock heads; hydraulics and springs.
.495" valve lift. Bolt-in street cam for light bikes (FXRS; etc.). Lots more mid-range and upper end power. 2800 to 6500 RPM cam with stock heads; hydraulics and springs. Smooth idle.
.510" valve lift. Longer duration for modified street engines with hydraulic lifters and 9.0 or higher compression ratio. Power range from 2800-6500 RPM. Improved upper end performance. OK for hydraulic lifters and springs. Note: Small base circle cam. Adjustable pushrods; or longer pushrods; are required to gain extra length to compensate for the smaller base circle.
.560" valve lift. Upgraded version of the earlier EV57. Fast open and close ramps for modified 80-88 inch engines. Very broad power band up to 6000 RPM. OK for hydraulic lifters; needs high lift springs. Note: Small base circle cam. Adjustable pushrods; or longer pushrods; are required to gain extra length to compensate for the smaller base circle.
.555" valve lift. Without inner & outer gears. These are available from S&S as 503606. An S&S (503566) or Andrews (503660) camshaft installation kit provides all parts for installation as bearings; gasket etc. For 96/103" engines with up to 10:1 CR. Use high-lift springs. 2200-5600 RPM. Note: The inner drive gears are not installed on Andrews camshafts and must be ordered separately. Installation will require specialty tools. Note: An outer drive gear set is also required for installing these cams and must be ordered separately.

.555" valve lift. Set includes two chain driven camshafts. A cam drive installation kit; that includes a gear cover gasket; cam bearings and retaining ring can be ordered separately as S&S (531691) or Andrews (503421). Cams can be run with stock hydraulic lifters. For 96 to 103 inch engines. Up to 10:1 CR. Use high-lift springs. 2200-5600 RPM.
Gives .470" valve lift on Panhead; .450" on Shovelhead. Street. This is the A cam with the longer exhaust duration of the Andrews B. Improved high end performance and reduced oil temperature in hot weather. Should install with no headwork.
