I just picked up the cam from a friend of mine for my wife's Yukon. It is supposed to be a 212/218 (XR265HR) high lift Comp. However when I look at the end of the cam it says 3706R/3652R HR113 D6(or 0)240. If I am reading the lobe numbers right this is a 234/238 .576 .585 on what I believe the HR113 means hydraulic roller on a 113 LSA if that is the case this cam won't do too well in a Yukon XL weighing in at 6000lbs nor with the LS6 springs I ordered to use on the XR265HR. Also it has 287 etched in it as well, which has me thinking it is a XR287HR which is a 238/240 but I am leaning more towards believing what I think are the lobe numbers. Please help me, I am supposed to drop this off at the machine shop to have installed in the LQ9 I have there being checked out tomorrow. Thanks
