400 will be EASY

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

my only concern is the vette has a very efficient drive line and im running an overdrive trans.

all respect dude, but the comp is in the engine. not looking for recommendations on cam choice, just thoughts on what i have. im sure eps profiles great shafts. anybody run that comp269 lsr ?

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.
