Default Why duration but not lift?

May be an odd question, but I am wondering why when a lot of people say what kind of cam they are getting the only say the duration? For ex. 232/232 instead of 232/232 .580/.580

Seems like you would want to hear about both. Help me understand.

Because duration will have a huge affect on power and how the car drives and idles. Lift does not that much effect on drivability. Lift is still important though.

They both affect cam lobe area, however duration has the larger effect.

here's a better answer: because pretty much all lifts for aftermarket cams are in the 500 range. People stay clear from 600's because they don't want that kinda "damage" on their valvetrain, . . . not only do they not spec the lift they also don't state the lsa, . . again because people generally stay in the 112 to 114 range, . . if it was a 110 they'd mention it, . . .and lsa has alot to do with overlap and hp and tq also

Yeah I guess I can kinda see that, but I just assume list it all, really helps for people like me that are still learning about cams. I am getting there for sure, jsut kinda wondered why people listed it like that. Thanks

People are lazy plain and simple. Plus I think a large percentage of people who mod cars car know very little so don't even realise that they are stating only part of the info.
