318 Camshaft
If your engine is stock or with nothing more than a 4bbl. and header bolt on, you will like the cam for repeating a stock feel with more power. You'll notice it. But not a big gain.
Those spec's are like a "Enhanced" cam, not far removed from stock duration but a big help in the lift department. This will add some nice HP numbers since it is getting into the heads best flow area. Something a stock cam doesn't go near. The extra exhaust duration is also good. This will help it breath better. The new intake charge will be cleaner and fresher as the exhaust is longer to rid the engine of the spent gasses.
You did note the RPM range of the cam right?
