Since this is next on my agenda, I'm looking for input and recommendations. I've heard of Suncoast, ATS, HTS, ATFSpeed and others. What works? What's tried and trued? I would like to find something that would hold up to 850 RWHP and 1000 Ft LBs of TQ and be very streetable. I'm not interested in neck snapping shifts all the time. A GM conversion would not be out of the question but I don't want to be the first one. Thanks.
