lift for which one, intake or exhaust? at what RPM? this is what most of us here wants to learn, so that next time we can read the specs of the cams and know which one is the best for our requirements..

use the internet: http://www.allmotorhonda.com has the best b series cam specs i have ever come across.

besides the lift and duration, u would want to look into the cam lobes ramp angle and overlap period. Although the overlap period can be adjusted using adjustable cam gears, these 4 factors basically determines whether which cams are suitable for your engine.

cams with low ramp angles are easy on the valvetrain, but gives a little less power, vice versa. High overlap period good for top end power, but sacrifices the low and midrange power.

cams like buddy club 3 has very nice paper specifications but only perform a little better than type r cams, because of the ramp angles and overlap timing. the lift and duration should only be used as a rough estimate of what u r lookin for, and not the ultimate deciding factor in looking for cams.
