TKO 600 ....Anyone done one?

Todd, which final drive ratio did you get and why do you have the TKO 500. It sounds like you haven't had any shifting issues, what are the particulars of your car:
HP, gear ratio, 1/4 mile times. Are you glad you did the conversion? I would love to see a picture of the modified case to do the mod myself, I have a machine shop and work with billet aluminum all day long so I don't have a problem cutting into the case so long as I know I'm not doing it in a place that would compromise the structural integrity of the transmission. Thanks, Kev
