Duration of Cams

[Taylor]

Putting my 12 hp Briggs back together this morning and looked at the cam and it seemed not to have much lift/duration.... I was possibly thinking that a 14.5 Briggs OHV would have more duration then a 12 Flatty ? I wasnt sure if of this because I know kohler k-series they use a 18 hp OHV kohler can because it has more duartion... Its just a thought and if it did I think it would give the engine a little more power and help get up trail a little better.

will the flatty even fit the OHV or vice versa??
 
sounds like a neat idea.

go to harbor freight and for like $30 you can get digital calipers, then you'll know the answer about the duration.

im pretttty sure they dont interchange... not even the 8hp and the 10 hp interchange...

Speeddemon,
8 and 10's dont interchange because the cams are diffrent sizes.... The 8's have smaller cams and the 10 interchange with 11 &12 hp FLATTY's.

Ryf,
I have all the dial calipers but I dont have a OHV cam thats why I asked first before going through all the effort...

[speeddemon0308]

yes.. and flat heads and OHV's are COMPLETLY diffrent motors!!!! 
i have a 17.5ohv intek in my racer.. and the AVS style wont interchange.. and neither will the intek that has the oil pump...
