My car is my Daily Driver, I have LS6Heads/Cam SLP LS6 Intake, Headers, Exhaust, Custom Tune
If I was to go with the 228/228 .588/.588 112LSA What else would I need to upgrade? And What would my total HP be(Ballpark)

well there are things you should always upgrade while you are doing your cam swap.
Valve Springs
Retainers
Pushrods
Timing Chain
Oil Pump
As for power. I would put you somewheres around 380rwhp.

I am running a custom grind 230-236 cam and am at 400rwhp.
Roommates GTO has a 224-228 cam and is at about 375rwhp.
Both cars listed above are A4s
All I can do is guess. I would say 380 with a good tune, that cam, LS6 heads and all his other bolt ons would be a good estimate but things such as the dyno used and how strong the car is stock will all also come into play.
is your car an M6 or A4? I would say it is very doubtful that you have 370-380 rwhp with stock LS6 heads/cam/manifold. You could always go dyno it before hand so you can see your gains.Last edited by juiced99ws6; 12-08-2008 at 05:30 AM.

The cam is the GM hot cam p/n:12480033. I'm really pleased with it. I'll have to scan the dyno sheet later. Best time at the track was 12.34 @ 115mph on street tires gotta get my 60ft time down and maybe I can get into the 11's.
