Upgrading to POSI
My 68 C10 will eventually have a 700r4 installed and the 3.07 open will be replaced with a 3.42 or 3.73 POSI. Have not made up my mind on the ratio yet.
What units are you guys using for your POSI? I have been told the GM80 is good and bad and there are others as well. Would like to get your opinions. Thanks!
