Ok guys...spent some time searching, but its hard to find direct answers...you see alot of cams that are equal duration like a 224/224, then you see cams that are heavy on the intake...and some that are heavy on the exhaust. Could someone help me understand what effects the duration has on power, and why you would want a particular int/exh durations?...How does a low int/large exh differ from a large int/ small exh duration cam...also how do you determine the best LSA?...For this thread, lets think strictly naturally aspirated... Thanks for your patience on yet another cam Q...
