I've tuned a head / trex m6 gto, I know how they run. Im guessing you only want to hear what you want to hear though. 
T-Rex or custom grind???
Horrible advice.. If someone doesn't have the ***** to DD a car with a TREX/MS4/Etc along with the supporting bolt ons (410s or lower, 4000 converter or bigger, etc etc etc) then that cam is not for them.
Ever wonder why there are ton of big cam cars out there that get drug by MUCH MUCH smaller cam cars? That is the reason. People put these huge cams in and try to make it street friendly with a 3500 converter/373s/ls6 intake for money purposes/etc etc etc and it just destroys the setup. Where as a bit smaller cam you can go with those things and it is a perfect setup, making it faster.
This is a max effort cam, if you don't want to go max effort then pick another cam.. There is no arguing that.

Horribe advice, I'm just saying if this is a daily driver, you're gonna hate the street manners with the 4.30 gears in the auto. That's fine if it's a track car. Hell, my auto has 4.10's and I'm at 2800 rpms at 75 mph. I barely get to the 1/4 mile in 3rd gear with 27's. If it's an all out race car, then yes, go for the 4.30's.
Contact ed curtis I am running his AZPS02 (custom grind) and it is great for the set up u have I am also running a 100 shot soon to move up to a 150. my sig shows you what a H/C combo can do with that cam. DA of 4165 at 2500 feet altitude and a conservative tune on 91 octane.
I am going to run the 1/4 here soon since the N2O install (100 shot only) and I can pm you the results.

im no expert what so ever but i have the t-rex in my daily driver and like it. I have Kooks LT, ORY with dumps, 4.10 gears and a full spool. My car is an M6 though so im not sure of the difference in gearing compared to an auto car. My car made ok power with the mods listed and it was 98 deg in the dyno room "if that even matters". just my two cents.

Instead of giving that advice you should have gave another cam selection. Like I said, that is the main and number one reason we see so many poorly setup max effort cam setups.
I DD this for the longest time because I wasn't about to have an Ms4 car that didn't run what it should have.. (It would bitch slap most DD cars, and I mean truly DD, every single day rain or shine)
MS4
PRC stg 1 ls6
ported FAST setup
LTs xpipe 1 chambers before axle
410s (I had 26" tires so didn't need the lower gears)
4400 converter
2950#s
etc etc
It was kind of a pain to DD but I didn't mind it so much because the car ran hard.

i am good friends with Geoff at EPS and even he will tell you that he has grinds that have better drivabilaty and perform better then the Trex and he designed them all for THunder.
Give EPS a call

Carlos...this is Kyle. 3klipse. I know about the 03 cam lol. But the OP is building a track car, not a real street car. If he is thinking about a Trex, he might as go with the 03 or any other large cam on the market.
haha lol dint know it was u so u know my bike is at the mechanic hahaha. Fair enough.
I would also look at the Polluter Cam with the TFS heads. I think Tick Performance sells a package of those heads with the cam. Or maybe look at the reverse split cams that PredZ has been talking about (check his huge thread) and see if that might be something you set up might enjoy.
