I see tiny C4's behind 460s too. And if a person wants to win at the track then that's the way to go. A bolt in sprag for a 727 is under a hundred bucks. I hate to see people get sucked into the hype over these weak trannies by these companies trying to make a buck off 904 parts that come stock in a 727. I have plenty of info already in my brain from my own experiences so I am able to stick to the subject at hand. For a daily driver that doesn't need an extra tenth, you're way ahead with a 727. Why take a chance. Eventually it will go out and another rebuild is definite.
