Your car is heavy, your going to need a little more gear. Your not getting the full benifits of all your engine mods with the stock cam. My car runs the same MPH granny shifting or power shift, ALL the ET differnce comes in the first 60' for me. It takes a 2.0 60' to get me into the 13's. I leave at 1500/1800 on Firestone SZ50's (225 60 15's) Our cars are differnt but I hope this helps.
Good luck,
Earl
