Vengeance Racing 08 LS3 C6 goes 503/449 Stage II LS3 Cam/TEA Stage I LS3 Heads!!! Im sure some of you remember my write up on our 08 C6 Shop Car. We baselined the car, added American Racing Catted Longtubes/VaraRam/Vengeance Racing Custom Programming.
End Result was 425/425....
Well the next round of mods consist of the following:
Vengeance Racing Stage II Custom Camshaft
Comp 7.400 Hardened Pushrods
TEA/TrickFlow Stage I CNC LS3 Cylinder Heads
GM MLS Head Gaskets
ARP Head Bolts ( We plan on spraying this combo in the NEAR future)
We worked exclusively with TEA to develop a "budget head" that WOULD PERFORM well without breaking the bank. End Result is a cylinder head that retails for 1399.00 and has shown a LEGIT gain of 28RWHP.
The TEA Stage I head consists of CNCd Intake & Exhaust Ports/Competition Multi Angle Valve Job/TEA Dual Gold Spring Kit rated @ .650 lift/Ti Retainers/New Seats/Seals/Milling to customer spec (.010 in our case)
These cylinder heads produced almost 30 additional rwhp over our cam only #s!!!! We have a couple dozen LS3s making 475/430... These heads took us to 503/449!!!!!
Here is the graph from our bolt on results to the Heads/Cam Results.
I will post an idle/drivability clip as soon as the rain clears. Our C6 only has 566 miles on it so we are still trying to keep it clean
Complete list of modifications to achieve the #s above:
VaraRam C6 Induction
Vengeance Racing Ported Throttlebody
American Racing 1 7/8 Longtubes with 3x3 CATTED X pipe
MagnaFlow 3" Catback
Vengeance Racing Stage II LS3 Camshaft
TEA/TFS Stage I CNC LS3 Cylinder Heads
GM MLS Head Gaskets
ARP Head Bolts
180* Thermostat
Custom Programming by Vengeance Racing.
STOCK INTAKE
STOCK HEAVY CLUTCH
STOCK PULLEY
STOCK WHEELS/TIRES
STOCK WATERPUMP
End Result was 425/425....

Only one thing to point out Ron. This is the first time I have seen anything from your shop that lost low/mid power. I say this because I am curious about the 20 rwtq loss at 3750 rpms switching from stock heads to the TEA stg 1's. I further examined the graph and can see the loss of 20 rwtq from 3500-4000 rpms is greatly offset by having +40 rwtq @ 5250, +40 @ 5500, +50 @ 5750, +60 @ 6000, +65 @ 6250 and +75 RWTQ over stock heads at 6500 rpms. So rethinking my previous comment, I'll forget about the small temporary loss down low and be happy as hell up top. Unbelievable how much more torque the setup makes from 5000 rpms on.
I'd love to see this setup on two different cars, one with stock heads, one with the TEA. The TEA car would just walk / run away at the top of each gear.
Great Job Ron, sorry about the longwinded post. Damn I need to visit your shop.

Thanx guys!!! I was a lil shocked at the loss of power down low myself, BUT we went with a slightly larger camshaft and didnt mill the heads except for a clean up pass (.010)... If this were a GTO I might be a bit concerned, but in a 3300lb C6 Ill take the power from 4500 and up

Hell yeah Ron !! I'll take an extra 40-75 more rwtq and 25-100 more rwhp on the big end vs losing a bit on the low/mid end too.
Way to go brother !!!!! You and your shop seem to have done it again !!!

Good results though on the top side.
