Harold Brookshire was a great camshaft designer and contributed much to the industry. Most people know him from Ultradyne Cams but he was all over the place mostly behind the scenes the brains behind many companies. I never met him but talked to him on the phone a couple times when he had Ultradyne. He told me that he was the first to use a computer to design cam lobes. He said back in the day computers weren't readily available and he would rent time using a computer at a bank to design cam lobe profiles. He told me that he could make an aggressive lobe easier on the valve train better than anyone else, I don't remember everything he told me but one thing I remember he said was he could make the lifter slow down and close the valve gently at just the right point without sacrificing duration and was a pioneer in asymmetrical designs.
