Thanks Sweet! I will dig in and take a look. Good call on the 32 spline. I have to beef up to the 32 spline to mate to the 6L90 anyway, but I do plan about 400ish HP from my LS engine so it’s sn excellent idea.
My 205 case was mates to the TH 350 so I have the smaller bore up front. I’m debating whether it will be cheaper to have a machine shop bore it out or just buy another empty 205 case with the big bore when I rebuild it.
