I am getting an 02 trans am and am going to put in a 12 bolt with 3.73 and a 26 0r 28 inch tire. Am putting the bmr hevy duty trak pack on it and also will be spraying a 150 shot on it. I am looking at the yank converters and was wondering what stall speed i should get.

 

I vote for either a 3600 or 4000. The 4000 might be a little big if you plan on spraying n2o. I would call yank or fuddle and tell them what setup you are planning to run and they'll match the TC and STR for that setup. Just my .02
