thanks harbone and nova , I bought this car rolling and built the motor I had the trans built useing tci trans parts, the last part I bought was the converter. I gave tci all the info, complete engine info, tire size gear ratio etc. and this is the convertor they suggested. but I might try another one. I read that a 4 link works best with a shocking like a clutch or trans brake. I'm going to try a heavier spring rate to get more rear suspension seperation. :idea:
