myn old 55 chevy used to blow out 4 speeds on a monthly basis.when i finally sold her it had a whine to it that was saying goodbye. moving from tn to al. about that time i didnt know where to pick up any parts or trans. so i sold it.i quit building drag cars and started building street cars again. lot more fun and cheaper.i started running 350s and 400s with manual valve bodies. lots of fun and no clutch.now that my left leg dont bend i want to build another 4 speed car. lol go fiqure.
