    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.

    So you have around the same things as me, only you have a bigger cam than my LS6 one, and you got 405RWHP? Nice!

    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.
