My chilton says 252/252-33 deg. of overlap, .4 inches of vavle lift for years 89-93. For years 94-96 it says cam specs. are 264/250-31 deg. of overlap, .432 inches of valve lift. I found out reading an article on a 96 ram having the r/t package put on it's 5.9l said the stock cam specs. @.050 was 184/192 deg. and the chilton's adv. duration for that motor's cam is 264/274-36.5 deg of overlap. If this is true to find durations on stock roller cams @ .050 lift is:(stock advertised duration x.70= duration @ .050 lift.)

No problem,
It took me a while to find the info myself, especially the difference between the advertised and duration @ .050. Being that they are roller cams the mopar standard .85 conversion factor for flat tappet cams doesn't work. The reason is roller cams take longer to get on to the lobe, but when they do they take-off.
Glad I could help
