At what point do you reach the point of diminshing returns.

I have a 331 with the TFS top end kit (stage 2 porting by Foxlake) with the stage 1 cam.

I have to meet Maryland emissions so I kept the stage 1 cam and I am hoping for the best. There are a few tricks that I can do to get it thru if it is marginal. I have no desire to swap cams every two years for a 15 minute appointment.

I know that by using this cam I am leaving a lot of power on the table but it is a DD and strictly street car. Even so I still would like to squeeze it to the limit or close to it but still be able to pass the test.

What I was wondering is how far can you push the cam before you are screwed emissions wise. The stage 1 is .499/.510 @ 112. What specs are you all running and still passing emissions.

I have been reading and researching and have yet to reach a definitive conclusion. It always seems that there is some oddball factor thrown into the mix on cam manufactures websites or in magazine articles. So I come to the real world to find an answer. Any thoughts.
