stock injectors big enough?
You wont see near the gains with stock manifolds they will choke the hell out of that cam. And there will be a little more room with the coil packs and everything off. No would also be the time for a LS6 intake, you have to take it off anyway.
i have a 240 duration cam with stock heads and i ran out of injector (~102% DC) and i had the 28.8#. the only way to tell for sure is to get it tuned. i would have some ready if you have to drive far to a tuner or want it done that day for sure.
