Im running 35's, soa, sbc 327 to a 3sp and 3spd case. I am going to a TH350 and dont know if I should use a 3spd case as I have two and they are always popping up, or if I should do a split case or Gm case with a centered rear? I dont have deep pockets but I am pretty hard on it espeacially in the sand. I would rather spend a little more now and not do it twice with two different adapters. I dont plan on going bigger than 35's and am locked front and rear. Any help from people who have already been down this road would be much appreaciated thanks
