Rick, if your tranny is an SROD, its not a bad tranny. I have one in my 68 Mercury pickup behind a 300. Its held up pretty well and I'm not kind to that truck. On a Ford truck list I belong to there is a member with a 460 using an SROD and its still alive a couple years after first getting hit with all that torque. That Fairmont doesn't weigh much more than Todd Bertuzzi and Markus Naslund combined, so unless you plan on dragging the car that tranny will likely hold up for quite a while.I think you might have the wimpy SROD trans where 4th is an overdriven gear.
