Need A Little help Please

MSD pro billet, 110 fuel Autolite plugs. Can't give out mothers maiden name. lol. So what I'm reading is Maybe not enough cam, converter to tight , combo is totally wrong. Now the question comes where to start. Cam, converter or combo. Guess no real hard answer is there. Will sleep on it and figure out where to start or live with what I got. Hate to waste power that should be there. $$$ spent for little results. Just would like to get by second round 1 time.
