I have 1990 pontiac trans am with 355, the engine produced 420hp at 6100rpm
and 425tq at 4200rpm. I bought th350 for my car and was wondering what rear end gear would be best for me and also would converter would be right? the car weights 3200lbs with me in it. the car will be driven in town 90% and raced at track 10%, fuel economy is not a concern. i'm just looking for gear that will run me down the 1320 quickly and a street friendly stall converter that will get me a good launch. any suggestions would be awesome.
