I have the tko with .82 over drive.It also has the 3.27 first. I was using 3.91 gear and I could 1/4 better using 2nd to leave in due to the first gear was so low,thats with a 28" tire. I swapped to 3.23 and I actually get to use 1st gear for a productive amount of time.
My engine combo is 422 ci small block run 115 in qtr @4500' 98 degree weather. In Sac I ran 117 throw out slav crapped and could not get 2nd,or 3rd gear well. I am getting 400 + or - to the ground. I cruise at 1600 to 1800 in OD @70. Hope this helps some on youre gearing ?
