I was wondering about that. I heard it did well on LS1 and LS2 motors, so I jumped on a good deal on a used '08 Z06 cam.
2008 Z06 LS7 cam specs: 210/230 .561/.558 120LSA
The LS1Tech guys don't yet know what makes a good cam for the big valve heads. I'm pretty sure my old cam isn't a wide enough split.
Thunder Racing cam specs: 224/227 .563/.569 114 LSA
I'm wondering what others are using and if anyone did any LS1Tech-type back to back dyno cam swap tests.

ECS has only one blower cam, right? I'm wondering how an LS1 blower cam would work on the LS3 heads.
From what I can gather from forum searches, the cams and porting for the bigger heads haven't been figured out yet. Bigger cams and better flow numbers on the heads are not directly related to power gains.
I'll keep an eye on your build, looks pretty interesting.

The LS7/3/92 heads have a pretty bad I/E ratio, that intake to exhaust ratio, you can expect to do a 10-12 degree traditional split at least for NA cars, and close to 20 degree split on a boost car like yours, Bill. If you want give me a call, and I can spec you out something.

Thanks Nick, I was reading some threads where the vendors were getting closer to making LS3/L92 power with smaller intake lobes and slower ramps, but they haven't yet figured it out. It sounds like Synergy and LGmotorsports are starting to figure it out, but the art is not yet fully baked.
This Lingenfelter cam looks interesting; 208/230 .554/.546 121. No hope for lope though. Here's another; 229/242 .631/.631 114. I think that's too much lift for my Comp 921 springs, looks like a fast ramp also.
I gave in and bought a meth kit for added insurance. The blower setup is the same (17psi+ capable with the 3.2" 8-rib Reichard) and the cubes are only going from 347ci to 376ci.

I'm building my car right know. I built a custom warhawk with a APS system. Just getting ready to put the motor in the car and start on the install of the turbo kit.
232/226 622/608 114 4 degree advance built into the cam
Int open at 6 degrees close at 46 degrees
Exh open at 51 degrees close at -5 degrees
