I searched for this answer but couldn't find any info, please direct to me to a relevant post if anyone knows of one. I want a brief, or otherwise, tutorial on cam profiles; lift, duration, timing, etc, etc, what each means, their inter-relations and effect on engine performance. Any information gratefully received.
