it gets old listening to people blame a camshaft for very poor combinations. The sound of a lumpy cam is primarily due to overlap and any serious race cam we'll have a grip of it but stock converters, air conditioners, power steering and other creature features will not work with peaky high overlap camshafts if you throw in a set of Street gears and a heavy car you will have a pig. and the second big mistake that people make is putting one of these camshafts in a 8 or 9.0 compression ratio motor these camshafts rely on high compression to work correctly and to produce maximum power.
