I was under the impression the 5.2 and 5.9 Magnum roller cams were a bit hotter than the LA roller cam, which did, in fact look pretty near identical to the FT pre- LA roller cam.
I've asked in a few places if the LA roller version at least had faster ramps to take advantage of the rollers, but never got a definitive answer.
This info is not super easy to find.
This is what I have:
318 2 barrel 67 Hydraulic 390/390 244/244
318 2 barrel through 88 Hydraulic 373/400 240/248

318 roller cam Hydraulic 391/391 240/240
360 2 barrel 71-74 Hydraulic 410/412 252/256
360 2bb 75-up Hydraulic 410/410 252/252
