Are Hughes cams that good?!!!

They would have you believe that. They took an idea from the 70s, made it their own, and convinced a lot of enthusiasts that they indeed are the best for Mopars. The reality is that choice cost a lot of users in terms of engine parts because they pushed the envelope too far. Truth is, the right cam for your combo will meet all your goals including power, efficiency, and longevity. And more than likely the right cam doesn't need to be on the ragged edge of high rates of lift, which is really what Hughes touts as "unique".
