Here is some good info to read. This is from a Evo 8-9. Yes I know they are two different motors but I use the numbers as a reference to convert to DSM specs e.i. intake duration @ .050 lobe lift: 211.5 is universal on cam analyzer. So the breakdown speaks for itself and gives an idea of the real numbers vs advertised numbers.

It gets really good when they get to the Evo 9 FP4R cams on the cam analyzer. Here are the advertise specs of the Evo 9 FP4R version 1 & 2. Both have more duration then the DSM FP4R (from what I have researched every evo cam has more duration then the corresponding dsm cam).

If you want to cross reference here are some evo cams at 1mm advertised duration. Also Jun 272 peak lift is advertised as 10.8 but shows 0.41829 =10.6mm on the cam analyzer.

I will say this. I have to give props to Darren at FFWD. He is the only person my machine shop and I have ever seen that posted the true specs of cams. They have always been there. Most just dont understand them.
