Magnum 380HP Camshaft

Ok...doing my 1st 360 magnum engine. I have a 380 HP hydraulic roller cam. Trying to degree this cam in, only thing I know about it is

duration at .050 is 230/234 with a 108 LSA.....

I tried to degree the cam in using the MP method of .050 before and after max lift, add the two degrees and divide by two...I get 103 degrees...I am ok with that....but went I go to check the the duration of the camshaft...I am not getting close to 230 on the intake....

I am going to double check everything again...I just changed out degree wheels...I upgraded from the small compcams wheel...10 inch I think to the moroso 18 inch wheel...

Anyone know the camshaft intake opening and closing valve?
