Camshaft Lift and Duration Theory - JDMCars.com
www.jdmcars.comA long duration camshaft usually has a power band way up the RPM range (6,000+), and a race motor that sees frequent sustained high RPMs can really make a lot of power with that high VE. There is a tradeoff, however. A camshaft with a long duration doesn't run well at all at idle or low RPMs. At low RPMs the port velocities aren't
