If two cams have the same 0.050 duration lift and LSA but very different duration at 0.006 lift(advertised) and therefore different overlap what are the affects on idle, vacuum, and mpg? I am looking at about 215° @ 0.050
Cam 1 has 288 @0.006"
Cam 2 has 272° at 0.006"
Assume that the compression ratio is the same.

Thanks for your insights.
