bolt ons

Ok guys I know there a bunch of threads on bolt ons. So far I have the flowing:
LT headers full exhaust with high flow cats
Cold air intake
ported throttle body
Diablew tune
throttle controller
This is what I am considering:
Intake manifold-wonder if the price is worth it
E85, injectors the whole set up -wonder if the gains are worth the cost
upgraded rocker arms- again the same gains vs cost
Guys i am just considering bolt ons. Not going into the engine yet and no boost.
My car is a 2008 LS3 auto.
Currently my best at the track is 11.9 spinning on regular goodyear run flats. I know upgrade the tires. But other than the tires what would you do? Any thoughts?

Diablew tune-There could be gains here with a more in depth tune, like HP tuners or EFI Live.
throttle controller-OK
This is what I am considering:
Intake manifold-wonder if the price is worth it-Me I would consider a ported MSD of port your stocker.
E85, injectors the whole set up -wonder if the gains are worth the cost-I'm looking into going E85 but the gains would be between 10-20 hp.
upgraded rocker arms- again the same gains vs cost-This will not make a difference in power but will help rocker geometry, this can be debated (short answer here).

I would consider tires, like an drag radial and some skinnies up front then more seat time

Thanks Brandon. I think i will look into the intake manifold and the tires definitely.

Save your $$$$ for the intake manifold and rockers. Buy a converter, 17" Hoosiers, and a good dyno tune.
BTW, what CAI?

Blackwing SLP is the CAI.

By far the biggest bang for the buck will come from a good converter: Yank, Circle D, or FTI seem to be the preferred vendors on here. Lots of guys running 3600-4000 stall in their daily drivers. It will take some getting used to, and you'll need a good cooler, but boy, will it give your car a kick in the *** when you launch it!

wouldnt rock arms be internal engine component and not be considered "bolt on" ?

and wtv may be considered how does that upgrade give you better performance?

That's not a true CAI, but simply a different filter and housing. Something like a Vararam will give you about a .3 quicker ET, since it draws (cold denser) air from outside the (hot air) engine compartment.
