I agree that a cam that can pull hard to nearly 6000 rpm is definitely a performance type grind,the problem is there were a lot of muscle car era engines that came stock with a cam that fell into that category,so then do you consider that as the staring point or do you step back to the milquetoast base version cam.Some guys would consider upgrade cams to be the next step above what the top factory option was,this illustrates why it is so important to view cams based on their @.050 values so you can compare apples to apples,also make sure to include factory offerings sometimes you will find one that closely matches your needs and even though they will typically have slightly less aggressive ramps and will have a little less room under the curve,they will also be easier on your valve train so if thats really important to you it may be a better choice.When researching a cam choice it is important to make comparisons based on builds that most closely approximates your own,because as the amount of deviation increases the comparison rapidly becomes less relevant.
