S&S, Easy Start 583 (IOG) cam gear kit

.583" valve lift. IOG = gear-driven camshafts with internal and external drive gears. Complete kit with installation hardware, bearings and gasket.
Direct fit. For 88 to 103" engines with compression ratios between 9.7:1 and 10.5:1, and 106" to 124" engines with a compression ratio of 9:1 to 10:1. Delivers great power and torque from 3000 RPM. Range 1500-5000 RPM.
The 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, by means of a spring-loaded compression release lobe inside the camshaft. After starting, the compression release lobe retracts through centrifugal force. The only difference is during starting, as you will now be able to start your Big Inch engine electrically with no effort, without the need for large batteries and/or starter motors. A standard starter motor and battery are sufficient. When the engine is running, the camshafts operate as normal cams, with no loss of power, torque or anything else.
Note: The installation kit required for Easy Start camshafts is included only in the complete kits (IOG). The installation kit for this kit is available separately as 531268 and is compatible only with gear drive models.
Note: Only the 551, 570, 583, 585, HP103 and MR103 cam series are direct bolt-in; all others may require machining 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.
