Default Comp Cams Lsr lobe question

Was interested in new technology, doing research on the new Comp Lsr camshafts.

So... whats up with these Lsr profiles. I really don't see that much difference between some of the older XER lobes.



For example:

269lr HR12 Lobe #'s 13015r/13017r

269/277 advertised | 219/227 @ 0.050" | 143/151 @ 0.200 | 0.357"/0.361"




My XER cam after degreeing, Lobe #'s 3761/3763

269/277 advertised... same | 219/227 @ 0.050"... same | 143/151 @ 0.200...same | 0.356"/0.361...Damn close



So really, are they just changing names to boost sales or is there some voodoo tech I'm missing?


Cam masters please chime in...

XE-R lobes run from 3720>3734

So the answer to your question is that the lobes you have were probably proprietary tailored after LSr or vice versa.
