TKB289 Tim before you buy a trans for the car, the to big questions are How much TORQUE and hp is your motor going to produce?? What rearend gear ratio are you looking at? What fuel system are you looking at, carb, FI system, webers? Are you going to keep this car for the long haul? If so, might you get the power craze and want a more powerful motor down the road? IMO the TKO 600 will work fine for your car. For first gear, you want something in the 2.80-2.60 depending on the rearend ratio. If the motor is stock and mild, get an steel flywheel. This stores energy better that aluminum for moving the car forward. 28-32 lb flywheel. Over drive ratio in the .80's to .70's. TKO has fixed some of the problem with there trannies. With a SB motor car, the ratio in the rearend would be a 3.31-3.54. Anything lower and your motor will be weak in grunt to push the car along at highway speeds. You want the motor about 500-700 rpms into the torque power band. This will give you the best mpg and easy accell without down shifting all the time. For my car I have a richmond 6 spd and race G-force 5 speed. I have 3.31 gearing and think it works best for the torque motor I have. IMO I think that Richmond still builds a better trans over all. Dad always said you get what you pay for and I still believe this to be very true.
