Question RWHP with these MODS???

Hi folks
I was wondering if somebody here has the following mods (or close) and knows the HP I could expect. 2002 SS M6 with LS6 cam, NC ported LS6 heads(by GM - 11.2:1), 36lbs injectors, large MAP, SLP Long tube headers with high flow cats.
any information would greatly be appreciated.
thanks
Bill

ditch the cats. get the off road pipes from ls1speed to match the slp headers they are $159.99 and they come with o2 simms. that way you can bolt your cats in at inspection time. that will help u alot. then get a cut out for $35 dollars and you should be real close to 400hp if not more.
