Hello my old combo with the Magncharger pullied for (9.2 lbs) made 403 on a Mustang dyno and 442 on a Dynojet. I have since went with Livernois Motorsports Stage 2 heads and Comp Cams 127350 cams. I do not know if the torque convertor will help went from a PTC .. to a Hughes Performance billet. I also while it was down went with a Melling billet oil pump and Trick Flow cam followers; which dont think its going to help out in the horsepower production.. The reason I am asking is my new turner street tunes.
