Went to the track last saturday

The MP .509 is not a small cam, tons of guys have run in the 10s with that cam, get the shifter sorted out, work on the tune & it'll fly!! Theres 11.5/11.6s @ 115-116 in that car all day long with what it has. I ran 11.teens/11.20s with less in my duster, with a 4400 stall it ran 10.9s most of the time. The torker intake i'd get rid of, The M1 single is a very good piece & works very well, you also may find a 750dp might run quicker.

When i ran 11.teens, granted it was a 451 lowdeck, but it shouldn't make a huge difference over a 446, this is what i had.

Stock port 906s with standard size valves, 9.7.3 comp., XE284H cam, M1 single, 750dp, 9.5" 4400 PTC, 4.11s with a 28" tire, shifted at 5600, trapped around 6000, Best MPH & ET was 10.91 121.56 on a 1.51 60ft., race weight was 3070.
