The PD 244/260 Supercharger Camshaft will have a heavy "lope" or "chop" to the idle and strong power through upper RPM range with emphasis on extended RPM capability. This camshaft requires a vehicle properly setup for upper RPM performance with modifications including: headers, free flowing performance exhaust, increased stall speed torque converter and optimum final drive ratio. Valve spring and pushrod upgrade are required.
