Anyone have a final drive for the co27 at SoCal? They told me about 6.3 to 6.5 but it was slow. I did not have my temp gun though so i really could not tell you how hot it was. i really have not run stock there before so i dont have anything to compare to gearing wise. I know i need to cut it and i have some Trinity xxx brushes i was going to put in. I really have no experience tuning stock motors so please let me know if i am off base.
