Anyone run a Comp 265 xer? Have a buddy trying to sell me a comp 265 xer. Specs are 212/218 .522,.529 on 112. Mods are in sig. I am just wanting something to add some torque and still use ls6 springs. If you or anyone you know have run this cam, please chime in.
Just remember that you are not limited as far as choice goes on cams. I would research a little bit more and get a few grinds that tickle your fancy as far as performance and driveability. Custom grind might end up being your best option, but who knows.

What defines a cam with xer lobes (no huge discussion required as I have a general idea xr,xer,lsk? I asked him again and he said he had the cam card. Next of all, the reason I am so interested in this cam is because I drive 300-500 miles per week and dont want to deal with a big radical cam. (Before I hear anything about big cams being driveable, I have been around plenty and there are always pros and cons). OH, not to mention the cam and springs/retainers are new and he told me he would turn loose of it for $225. There is no way I could get a custom cam for that money. Thanks for the input and Im not trying to argue, Im just trying to understand.

The cam is XR-265-HR (lobes 3751 and 3752)
The smallest amount of lift for a XE-R cam is .581 and lobe # 3720
Basicaly the cam you are looking at has what we call lazier ramp rate, it is very spring friendly and with proper matching combo can deliver good street power.

I see. I didnt know where the xer lobes started in lift. One more question and then I'll let it go, what do you consider a properly matched combo for this cam (heads are not an option). My car is an 01.

To make it optimized, I would yank the heads, put on a .040 cometic gasket.
That should make your DCR in the 8.6x range and give you ~10.5 SCR. It will also better your quench for less detonation. Also degree the cam.
That would mean a good 10>15 rwhp.
otherwise your setup is good. Maybe a ported TB, and a LS6 intake if you don't already have one.
