Co-workers LS3 C6 with intake/exhaust just put down 413/402 on a mustang dyno. With a cam 400 wont be a problem.

If your comp is at least 11:1 and you have the valve springs to run 7500 rpm to get to that intakes sweet spot you should make 400 no problem. I am assuming good exhaust, tune, and well put together engine. With the aftermarket efi and that intake you can go a lot larger on the cam in the future and get it to idle great. Way easier to tune than the factory pcm's.

it is a bone stock long block except of course for the cam. compression is 10.7 on the LS3 . i am running the recommended dual springs for the cam. comps claim on power band is 1800 to 6700.
