Swapped to 528 mech cam slowed down

It seems to me the solid is smaller than the hydraulic,you need to go up 10 degrees as a rule of thumb with a solid just to equal a hydraulic at .050 due to valve lash.Figure the lash in and you lost lift and duartion and I believe the mopar cam has a 112 lobe seperation vs. the comps 110 wich shifts things upstairs slightly so its apples and oranges.
