Quest for 430 rwhp
That's it. I've made a decision to get my 03 Z06 to 430rwhp. Currently Dynoed out at 381 rwhp with the following mods, LG longtubes, Xpipe, high flow cats, B&B Bullitts, Varram cai, had 80mm BBK SSI set up at time of dyno, now have ls6 ported set up. Considered either a nitrous set up but don't like the part time factor. Now considering heads and cam package and underdrive pulley. Found a great price on a Patriot Performance heads and cam package 225/229 .581/.591 114 243 ported heads but looks like that would get me 410ish rwhp??? Will I get boared with this set up? Is this an entry level set up? Do people move on from Patriot? Don't really want to pull heads and cam more than once. Will this cam give me the lope and sound that I am looking for? For $1650 do I pull the trigger on the Patriot h/c package?

You did not specify what lope and sound you are looking for. I would not think that cam will have as much lope as a cam with a smaller LSA. Also, that cam is on the small side as far as cams go. There are much bigger alternative - if that is what you are looking for.
You stated a rwhp # but is that all you are looking for? Do you want low end grunt, a flat torque curve, peak HP? Need to know more about your goals.
Patriot heads are fine for a budget build. There are better heads available but at extra cost. A package from a vendor can be a good deal and can include parts designed to work well togther.
Do a lot of research before you make any decisions.
Good luck

That's why I was asking the questions about Patriot packages. Kinda thought that once you get the taste of a cam you may have to move on.

Yeah, that's the problem i am having. Every cam maker claims that you won't loose driveability and it doesn't stall and they all say "as long as you got a good tuner". I think I have a good tuner but where are all the guys that were pissed because they put the cam in the car and no matter how it is tuned it stalls at stop lights and bucks at low rpms? What cams are these so I can stay away. England Green's whiplash II claims to be the best of all worlds. Bigger than G5x series and doesn't buck or stall "as long as it is tuned properly".

I went with the G5X3 on a 112 LSA. It lopes alot
- what a wonderful sound. It has a great power band for me (I have 4.10 rear end) and can get in the power band quickly and stay there.
It drives very well - it has stalled on me 2-3 times total in the past 9 months. There is only slight lugging sometimes in a parking lot when I am trying to go very very slow in 2nd gear. Just put her in 1st and no more problem.
I have a combination speed density tune (low rpms) and a maf tune (highter rpms). I have a great tuner. The ride really is in the tune. If you have a great tuner - ask him/her. They should have experience tuning various cams and combos on an LS engine and be able to point you in the right direction.

All you need is a cam. Check out the LG G5X2, G5X3, or one of England Green's cams. A cam added to your current setup will definitely put you over the 430rwhp mark.

If you want lopey, that cam won't be lopey.
225/229 .581/.591 114
get something in low 230's and get the LSA (the 114 in the cam spec), down to at least 112. A good tune will prevent the stalling and crappy street manners.

I have a 224/228 581/588 112 +4 comp cam. With a set of ported 5.3 heads I made 409 rwhp and 405 rwtq. If I get a ported fast intake and bigger injectors I should be above 430. My current injectors are at full duty cycle.
My 112 is mild at idle and it does not stall. I have to half clutch it under 10 mph. Power is great throut all the rpms and I did not want to go bigger because I do not want to lose any power under normal driving condition (low rpms). You will get alot of valve train noise with the bigger cams. Sounds like a sewing machine.

If u r looking for lope, chop at idle, good driveability and yet produce good numbers than:
AFR 224/228 588/58x 114 LSA
ECS N/A cam,
FTI (flowtechinduction.com) HT cam 228/232 612/600 111 LSA.

Man I'm soo confused. I am soo close to pulling the trigger on the England Green Whiplash II cam package at $1595 including oil pump and u/d pulley. All these cams sound great. I have also looked at the LG g5 series cams as well. Sounds like you get more for your money with EG package. England Green claims the best of both worlds, driveability, and power above about 3400 rpms. Again, I don't want this car to be a burden to drive it around town and I got to have the lopey idle. Now what's my best bet?
