I am considering replacing my 200R4 w/lockup for a 6 speed manual. Tranny is awesome for drag racing but, I miss banging gears. Wondering if anybody has experience with this conversion of an automatic car to a Tremec Magnum 6 speed and who sells the best conversion kit. I am running a big bore small block 377 dyno at 450 hp and 7000 rpm shift points. It is a console car and read a lot about shifters leaking on the Tremec that align the shifter with the stock 1969 position. Any feedback is appreciated.
