The term blower cam is a little outdated when it comes to the 3v camshafts. Old school it meant something becuase n/a cams were n/a cams. every cam out for our car is a blower cam in the classic deffinition. Except Thumprs and Hot Rods, even the hot rods could work. But why do it.
The off the shelf cams they call blower cams now are really high boost cams. 15psi or more. they tend to just have more lift if you compare comp specs, maybe a little less overlap but not much. And a little more exhuast dur. Are you running more then 15psi? Your going to have a engine builder anyway then.
