they are all good options. just need to know what you want and how much work you want to put into it. i like the silver sport setup. i was even willing to do it after they said their kit wouldn't fit my 273 because the starter is on the wrong side and they couldn't match the flex plate bolt pattern :rolleyes:... but now i'm back on GV.
