do i need need a bigger carb

If you have a carb you can try it might be worth a shot. My 410 stroker only has a 750dp on it (and about 1 point less compression), and it runs 10.8's at 123 MPH....I would love to try a bigger carb, I just have not had time to mess with it.

Something seems off though...did you degree that cam when you installed it? I would think your car should be about a half second faster.
