2002 6.0 Questions My engine is out of a HD 2500 Chevy truck and I wanna say it's a LQ9 plant.
I'm replacing the OEM bump stick with a Comp 54-426-11 http://www.compcams.com/Company/CC/c...csid=1090&sb=0 bump stick.
Whilst I'm in there, I plan on replacing the timing chain assy. Looking at replacement sets has my eye's bleeding some from all the choices.
What would you folks recommend using?
Does this cam require degreeing also?
This engine will be used in an off road tube chassis buggy trailer queen. I have the putor flashed for non emissions and no trans communications (old school TH400). I realize I'll need to have a run tune done for the added bump stick as well.
As I move along, I'm sure I'll have more questions for stuff I haven't found searching. Also, This site does offer a bunch of great info.

my cam is only slightly more aggressive and I'm running an OEM Cloyes LS2 timing set, however this is non adjustable.
I would not use a double roller in your case. You only need a double-roller if you have one or more of the following:
1. sustained high RPMs
2. Aggressive lobes, high ramp rates
3. high lift
Also, if the engine is a 2002 and its from a Chevy, then it is likely an LQ4. Only difference is LQ4 has dished pistons, and LQ9 is flat top. You'll be able to tell pretty quick.

I would call one of the vendors here, and think about a custom grind cam. I think that you could go much bigger and still be dependable. With the right valve springs, stall, and gears of coarse. I second the lq4, as mine is a 2002 out of a 2500 hd. Thats not a big deal, it only about a half of comp point. these things will run great anyways!! Sounds like fun in a buggy!! My next ls project is going to be a truck or buggy!
It's a LQ4 block, crank, LS2 pistons, Polluter St3, 243 heads, LS2 timing chain, BTR valve springs & lifters and for now a LS6 intake.
