'09 LS3 21st CMC Stage III Cam results!! Well I dropped my '09 LS3 c6 off at 21st century muscle cars for a cam install.
This is their Stage III cam for the LS3. My car is the highest dyno so far with the setup most are around 480rwhp.
Cam only. Stock/untouched heads.
227/239 .629/.623 114LSA
Callaway honker intake
Ported Intake/TB
UD Pulley
American Racing headers w/ catted X-pipe
400 miles on the car.. so hoping for 490rwhp with cooler weather and more miles.
This equates to 560hp @ the crank!
Here is the new store front when you walk in:
Drivability is amazing. It's not stock.. it shakes at at a stop but nothing crazy for me anyway.
Great experience dealing with John Page and his team. I highly recommend them.

It does really well. The does good under 3.. but at 1,100rpm cruising it can buck sometimes. 21st century is going to try to tune that out.
It is remarkably tame vs my g5x3 I had in my old '01 z06. I couldn't run the A/C in that thing. This new one I can have the A/C on full blast and go from a stop without any surge or bucking.
