Actualy, a tunnel ram with carbs that are set up right, are not a dog on the street, and almost always make a big boost in tq. Its about line of sight, a direct straight shot, and, the runners are longer, which boosts tq. 99% of the time tunnel rams get a bad rap, is because the carbs and distributor, aren't set up right, and the run like crap by default, it has nothing to do with the tunnel ram.
