There are cam's that made solid 500rwhp or over, but you have to decide to which intake you will use (EFI Stock LS3, EFI Ported LS3, EFI GM signle Plane, EFI Edelbrock signle plane, EFI Edelbrock dual plane, EFI Holly signle plane, EFI Holly dual plane)

-Spinmonster (In Corvette Forum).
-RPM.
-LG.
-Thunder racing.
-Cam motion.
From reading the LS1tech forums, there are many posts about Patrick, PRM, Thunder racing and LG cams doing minimum of 470 rwhp and up to as 517 rwhp with 6.0 Liters engine.
By the way these LS3 heads love compression (CR).
As advised, try to approach Patrick G, RPM, LG and Thunder racing and they will sure help you in what you are looking for to achieve your goals.
I hope this will help

If its a stock crate motor I would go with Texas Speeds 231/236 cam. Thats what I have in my stock LS3 and Im very happy so far. Great torque at low rpms and just pulls like a train up top. Seen a couple C6's running high 10's with this cam, cam only too. I got a 114lsa yet it still has a nice lopey idle. A 111 or 112 might be what you want. This cam is a good size cam for an LS3 due to the tight ptv clearance due to the huge intake valves. With some of the other bigger cams youll be cutting it close...if youre not touching the bottom end.
Ive only heard good things about Pat G but personally I dont agree with paying $25 for a service that any good shop does for free. Of course people are gonna be happy because theyre gonna feel a difference in performance with a good cam. Unless the money goes towards the purchase of the cam if you buy it from him, then maybe. JMO.
Don't forget about Geoff Skinner@ EPS either. Pat G has worked with him on a few things in the past regarding cam stuff. Pat G sometimes uses Geoff's proprietary lobes on his custom spec'd cams
I have spec'd several LS3 cams and many other cathedral port cams with good results. I just spec'd a stock stall G8 cam with a L76 yesterday for a friend of mine's wife. Should do really well.
What do you want to do with the car other than it being a driver? HP goal, mph goal or E.T. goal?
I can get you in the right ball park also if you would like.

As it is sitting on the rev limiter some 40 yards before the line I am looking at trying 274/45/18 M&H tyres soon.
The last pass I made I let the car shift into 4th gear which lifted the speed up from previous 120.xxmph to a little over 121mph so it may have enough power to use the taller tyre.
