S&S, Easy Start chain cam set MR103 (CD)

.585" valve lift. CD = Chain driven camshaft, complete kit with gasket and bearings.
Direct fit for stock 103" engines with a stock compression ratio of 9.7:1CR up to 10.5:1CR. Works well with unported heads and is ideal for S&S CNC ported heads. More power across the entire RPM range. 2500-5500 RPM.
Easy Start camshafts make starting easier by reducing the build-up of compression pressure in the cylinders during starting. This is achieved by slightly lifting the exhaust valve off its seat, via a spring-loaded compression release lobe inside the camshaft. After start-up, the compression release lobe retracts by centrifugal force. The only difference is during starting, as you can now effortlessly electric-start your Big Inch engine without the need for large batteries and/or starter motors. A stock starter motor and battery are sufficient. When the engine is running, the camshafts perform as normal cams, with no loss of power, torque or anything else.
Note: Only the 551, 570, 583, 585, HP103 and MR103 series camshafts are direct fit; all others may require clearancing and need high lift valve springs.
Note: Not compatible with kick-start models.
Note: Only camshafts manufactured before January 2010 will require adjustable pushrods.
Note: Below 900 RPM a clicking sound may be heard. Adjust the idle speed to 1000-1100 RPM.
