I am installing a LS1 in a TJ Jeep, Dana 60's, ARB lockers 4.88's and a 700R4 with a 1700 stall running 40" tires. The LS now has LS6 243 heads,Pattriot Gold spring kit, LS6 intake, S&P shorty headers. I am afetr torque, the cam is Comp Cams 54-412-11 "Xtreme RPM" Hydraulic roller camshaft. I am using an double roller timing set and my question is:
- should I advance or retard it from the stock setting
I have it apart and wonder if anyone has used this cam ? I would rather go small than have a cam that would not perform in the lower end.

RPM range: 1,200 to 6,000 rpm.
Duration at .050" lift: 212/218 (int/exh)
Valve lift with 1.7 rockers: .522"/.529" (int/exh)
Good torque and mid-range power.

compcam has a camshaft dyno simulator,go to their website and down load it and try different can grinds.I was looking at grind #54-408-11,this one made the most low end for my combo.

Do you have an adjustable timing chain where your can advance or retard your cam??

Your really not going to make a huge difference with this, Id just install it straight up. Almost all aftermarket cams come with 4 degrees of advance ground into them for you, which help torque.

IMO even if your going to run a cam straight up you should still check it with a degree wheel I have found a few that the center line was not correct and needed a change.

Never assume the timing gears are accurate. I have seen them up to 10 degrees off-and that was a cloyes set. Its worth the piece of mind to degree the cam.

FYI be careful when advancing or retarding the LS motors. Depending on your combo you may get some valve clearance issues.

I just finished a LS6 for my TJ. I retarded the timing by 2 degrees. First start up bent all intake valves.

Just be sure you konw what clearances you have
