LS3 cam selection giving me a headache!
LS3 manual trans street / Auto-X / DE car with headers w/high flow cats and Halltech MF103, tuned for 93 pump.
Needs to be docile in town but pull past 6500rpm. Will install thinner head gaskets and upgraded valvetrain with the new cam.
Which one wins, red, white or blue?
230 XFI / 234 XER
114 LSA
112 intake center line
.615 / .600 lift
4 deg overlap
225 / 235
114 LSA
110.5 intake centerline (114+3.5)
.621''/.604'' lift
228 / 236
112 LSA +2
.615"/.615" lift

I'd consider the first one only if ground on more modern lobes. Tx Speed or Cammotion can grind it for you. Cam number 2 sounds interesting. I have a 226/234 115+4 in my LS3 and like it a lot. I wouldn't consider the third cam because I think it has too much overlap for a street car. Higher overlap translates into manners that are less than what I find acceptable in a street car. That last cam has 8 degrees of overlap. I had a cam with 9 degrees of overlap in my first LS3 and couldn't wait to get rid of it.

I have similar plans with my car. Just had the BTR stage 3 installed along with ported heads and Intake/TB. It put down 512/464 on a mustang dyno and has a great mid range. I had the larger BTR 4 before this cam and i am liking the 3 so far.

May I Suggest 2 others for your consideration.
If you are ~35+ and prioritize street manners & auto x VS Track,
for a daily driver.
Cam Motion Titan 2 LS3 222/230 113+3
If you are younger than ~ 30 and want a little more radical cam better for track but
still daily drive able
The Titan 3 227/237 113+3
When choosing between 2 Cams.....
The aggravation of a cam a "little to big"
FAR out weighs the disappointment of a little to small,
Especially for a Daily Driver.
just my .02
Good Luck

Spins 230/234 imo....
I called Texas Speed and had them grind it. 230/234 .615 .600 114+2, this came seems to make around 480-500whp on stock heads and drive like stock almost.
I have ported heads on mine, its headed to the stop/dyno here within a week.

I second the vote to go custom cam, like from Ed @ Flowtech. He can spec a cam with tq down low for AX at the same time carry the power well into the upper range. 
And are not all [the listed] cams too big for AX in a 6.2 ?

Update us on the results please, I'm very interested as I'm also thinking of doing spinmonster's cam although I'm not sure whether that will be a good cam for HPDE & AutoCross which is what I'm planning to do with my GS. Probably will do the heads too as I want to increase compression like spin recommends. Are you flycutting the pistons? I'm thinking of doing a smaller port head for faster flow and better under the curve power but not sure what head to go with; it probably will have to be a cathedral port head. Who did your heads, did you mill them? Thanks

Of the cams mentioned in this thread....IMHO:
#1 Choice is Navy Blue's suggestion -- The Titan 3 227/237 113+3
#2 Choice is your 'white' cam -- 225 / 235 114 LSA + 3.5
Their IVCs are 43.5* and 43* respectively
Their EVOs are 54.5* and 55* respectively
The Titan has 6* Overlap (Less than my daily driver) while your 'White' cam has 2* overlap.
Both with provide strong torque off throttle....and will carry to the 6500 rpm range.
The Titan should make a bit more power top to bottom while being very manageable for street driving.
The 'White' cam will be a strong runner, but it may take a well trained ear to discover that the car is cammed….fairly docile until you 'hit it'!
Best of luck whatever you do.

The Titan 3 227/237 113+3 is a mean cam but it is more aggressive than the TSP Stage 1 (225/236 .629"/615" 114 LSA, 109 ICL) and hearing the YouTube idle clip makes me think even this Stage 1 is too much. Does the TSP have a lot of overlap? Maybe I need the Titan 2 or the White cam on my list (225 / 235 114 LSA 110.5 intake centerline (114+3.5) .621''/.604'' ) ?

OK.....jokes aside....you're probably gonna need a custom cam. Something along the lines of:
230*/246*, 114.5* + 1*, with about .625"/.625".
Low RPM not gonna be so strong, but it will be a bit better than stock.
With the right intake work (or swap) this cam should build power close to 7K rpms.
Has 9.5* to 10* of overlap....so it's gonna buck surge a lil' bit....even with a good tune. But that's the cost of business when you want power past 6500 rpms
All that said, I HIGHLY recommend that you give Cam Motion a call and have them spec and grind you a cam to fit your wants!

That's awesome!! How did you manage to hit 470RWHP without changing the cam or the heads?

Every bolt on and in imaginable lol I used psi1511 valve springs with 1.85 rockers, crank scraper, headers, ported rod mod LS3 intake and ported throttle body. Mezeir water pump, ethanol, ati pulley, lsa injectors. My set up had a 5.5" triple disc tilton clutch at the time that weighed 16 pounds complete. I had 4.10 gears in the C6 and stock 3.90 in the 1LE.

SWEET!!! You should have added ported heads as well. So how much power you can make with the stock cam!

I dropped a valve and ended up getting GPI ported heads and SS4 with the LOD x1 intake it made 560 whp. I chased my tail all year trying to get my combo sorted but just not enough gear to utilize the 78-8000 rpm shift points. Went 10.62@134
