Walt and wally are working with me now on a new clutch set up. their ability to help over the phone is second to none. I first had problems in 04 when i puschased the stock tko 600 and could never shift over 6500 rpm I called walt and he told me what the problem was right away. So I sent him my transmission and 5 seasons of shifting over 8000rpm are the end result. Rarely miss a shift and all the guys at the local track still can't believe I'm driving a clutch assisted car. you can check out video's on youtube search nos347stroker and my videos should show up. Don't forget I'm only 331 cubic inch 300 shot I,ve been using a proshifted tko 600 from promotion for 5 years now without a problem running 9.20’s at 148 on a 3000 lbs car. quality is unmatched as far as I am concerned.
