Ive been reading on here and seen some post that say that this cam comes with XER lobes.....Does any one know for sure or know where i can find out? I have this cam but havent installed it and just wanted to know that way i knew what to expect out of my springs.

 

this was the first cam i ran in my vette. i had it on a 112 LSA and i went from 353rwhp 366rwtq to 396rwhp 377rwtq after switching to this cam which equates to a 43rwhp and 11lbs-ft tq gain after the tune. Also i ran the comp 918 valve springs. I also picked up 4mph in the 1/4 and .3 on my E.T.

 

I have no idea, I just installed that cam this past weekend and it sounds aggressive. Might call Gunnar up and ask him, I'd like to know as well.

 

XE-R. If you have any questions, please let us know.
