Are Hughes cams that good?!!!

I know it's all about the combination that makes the engine, but the cam is the brain. Knowing the power output at given rpm range of someone else's engine combination, gives me an idea on what to expect from mine

I understand. Do the math from Tony's drag strip times. Plenty of online converters that will tell you HP from the info he gave. Even still, his car is not yours, so it's all relative. That's why I always discourage people from the numbers game.
