Here are two new dyno results for our G6X-3 cam package. One is a cam only with LG Pro Long Tube Headers, and a K&N Cold air.
Both graphs are with a K&N cold air filter
The other one has small Stage 1 heads, that have just a competition valve job and it has the compression up a couple of 10ths.
Our mission was to get good drivability and not only keep the power in the 500s but to increase the torque to a level that is well above a stock Z06.
G6X-3 CAM ONLY 501rwhp 470 rwtq
Cam w Stage 1 heads 517rwhp and 484 rwtq
Making this kind of hp was a goal that we were hoping for out of the LS3. These numbers are just the beginning. We will be putting a set of fully ported LS3 heads on the car next. The heads will be finished in a few weeks in their final form.
We will be offering 3 stages of LS3 heads for our packages, with the Stage 3 as the max.
We look forward to reaching the 550 rwhp plateau soon
Thanks and we will keep you posted.
PS the drivability of this package is already more than acceptable. You know it has a cam in it but the drivability is really surprising as is the power that is just available everywhere!
Black 08 This is a G6X-3 Cam only in a slightly different version that we did to bring the torque up. As you can see, we did accomplish that by getting 470 rwtq while still keeping just over 500 rwhp.
Silver 08 This car has Stage 1 heads, meaning just a Competition Valve job and a touch up with a couple of 10ths more compression 11.3:1
Wow, impressive results. I've been dreading the day a cam only C6 would hit 500, because that means I'm probably gonna need a blower, turbo, or nitrous to even think about winning the race. Might as well skip a new h/c setup all together, haha.
can't wait to see what fully ported heads LS3 heads will do on the LS3
I can't give out the source but unless you are running an adequately sized cam the ported heads didn't do anything. I know it sounds amazing but that is what I was told. I will say this though, my source is testing larger cams and are hopeful that further testing will yield much better results. Stay tuned.....

Louis I thought you had moved past the G6x-3 and was using the G7x4?
Whats the big difference between the G6x-3 and the G7x-4???
Which would offer better overall numbers?
Do either one of them require flycutting on an L92 engine? I know the L92 has slightly lower CR pistons, but mainly it's from having valve reliefs from what I'm told. By my assumtion that should give me more clearance than what the ls3 is dealing with, correct? Could I go with some thinner cometic head gaskets to make up for the CR offset by the valve reliefs?
I've got a L76 intake that I'll be porting and using until the FAST comes out.
I'm gonna stick with my stock 5364 casting L92 head for now with just the req'd valvetrain upgrade.
Also, my car is an M6 02 WS6, with a 3.90 12 bolt. Is that enough gear for either of these cams??
