Best CAM for an otherwise stock '04 LS6 Hey guys,
I have a stock '04 LS6 crate engine that is going in a 2500lb project car that is going to be a road racer (HPDE) as well as a cruiser. It will probably never see a 1/4mile track. The exhaust will be a long tube design and there won't be any CATS in the way.
So the question is: If I keep the stocks springs, heads and intake manifold, which CAM would be the best choice to take advantage of the better flowing exhaust. Obviously a tune would be in order. I still want to be able to run the engine up to 6500 or above.
Thoughts? Limits on the springs?
Thanks,

Youll have to change the springs, no ifs ands or buts about it.
How high are you willing to spin the motor on stock shortblock and more specifically, stock rodbolts? You can probably put a good size cam in there and itll still pull itself out of the hole being so light... Although you may not need all that being a road racer. Might look into a 224/228 sized cam and spin to 6600 ish to start. Theres a ton of cam options for you. Where are you looking to make power?
EDIT: I forgot you said LS6. With LS6 springs there are a few cam options, but IMHO anything worthwhile will require a spring change.

You could run a LPE GT2-3 on those springs or Old Man Cam. Otherwise Yeah spring change is a must.
If you have no heads change in the future, I would run a 224/224 .609/.609 111+2 LSA with duals. That is a good midrange to upper rpm cam and good all around trq producer.

Wife's GTO has has a GT2-3 and she loves it. Makes good power over stock all around, even on stock (LS6) Springs and stock manifolds, but still idles nice and doesn't require huge $$$ in supporting mods.
You may also consider a custom low lift, high duration cam to avoid the spring swap, but if you don't mind a spring swap, there are tons of options.
You may also consider one of the reverse split cams mentioned here:
