This article may be of use to you: LS Cam Test Comparison - Car Craft Magazine

They dyno, among other cams, a LQ9 in an LM7.

 

Id seen that but thought the cam was bit smaller in the LM7 than the LMG...

 

Always saw the 6.0 cam were slightly larger then a 5.3 4.8 cam

If you ever listen to a stock 6.0 idle you can hear it has some cam to it vs a 5.3

 

Im gonna run with the lq9 cam i have, thanks guys.... Yeah i have noticed that, george, that the 6.0s always sound better....

 

If installing that cam in a gen4 motor you will need the vette cam sprocket

 

Yeah i found one for something like $20, have you had any experience with melling lifters??

 

I prefer GM lifters

Except for my 427 which uses tie bars

 

I do too, however with price i can get mellings for, think i am going to give then a shot, i know they make a good oil pump, lifters cant be that bad....

 

If you can get your hands on a LS2 cam it will give you a good bit more mid range and top end.

 

As stated i have the lq9 cam already, and im not necessarily looking for anything other than to just get rid of the dod in this truck, as inexpensively as possible.... Ive heard that the ls2 cam needs different springs too..... If i was going for max performance i would probably go with an ls2 cam or get comp, btr or whatever but this yukon is the daily driver/kid carrier/roadtrip vehicle at this point so not looking for much out of it, maybe lil bit more hp and tq but not trying to really build this one..... At least not right now...when i get the tune done its goin to be geared toward regular gas...and mpg...
