I haven't been able to find new replacement LA rollers with stock lift specifications but putting an LA cam into a magnum makes a noticeable improvement if you have a usable stock LA roller on hand. The LA 360 is your first step up the ladder and the LA 318 hydraulic roller would be the hotter cam choice. There's usually a crosswind type intake involved in the mix whenever I've been involved with the swap and it makes a before and after difference you can feel. I will have to find the stock lift chart to share with you for the specs but here's a W100 with a 5.2 Magnum and 360 LA roller with a crosswind and a 650 Edelbrock. It's got 31X10.50 and 3.21 gears with a HD four speed but there's no shortage of torque. Lower gears would really help, though.
Not sure if I would use...or maybe, stock specs on LA, LA-pre mag, and mag cam specs would be interesing side by side. Just for fun. Mine is a "re-grind" for my 5.9L is by Bullet Cams, .525 lift w/ 1.6 rocker, .218 and .226 duration, 112 LSA. Eddy RPM performer intake. EQ heads w 2.02 SS intake. 1989 D100 2 wd. What about that Duster in the profile pic?
