HR are not a waste IMO. And they make power over the bottom of the food chain HFT cams. They have a much better ramp and lobe velocity, plus you have the added bonus of less friction and longevity with the more aggressive ramp. HFT cams are ok, but they are the bottom of the barrel as far as cams go. In all my testing over the years I have found that its not always about how much peak power you can make but rather the power under the curve. You might only pick up 15HP at 5500rpm, but you can pick up 50HP at say 3500rpm. Thats where its at. I have had very good luck with HR and even better with SR cams.
