There seem to be at least two Boss 302 cam specs, DOZZ-6250-A (290* duration, 58* overlap and 0.477" valve lift) and D0ZX-6250-B (324* duration, 114* overlap and 0.589" valve lift). The second is more like the B2 spec I remember. The first seems like a solid lifter version of the standard hydraulic lifter C9OZ-6250-C over-the-counter cam.
I hope this helps. Sorry I don't have the specs for the Le Mans cam. I do have more complete specs for the B302 cams listed above if needed. I'm sorry I don't have the source listed--this was something I have on an Excel spreadsheet from long ago.
