Explains in simple language how to choose the right camshaft/s for YOUR application and how to find the camshaft timing which gives maximum performance. Also explained are all aspects of camshaft design and the importance of lobe phasing, duration & lift. Applies to all 4-stroke car-type engines with 4, 5, 6 or 8 cylinders. Avoids wasting money on modifications that don't work. Applies to road and track applications.
