Has anyone done this? I was hoping Ford would step up to the plate a few years ago and offer a T-bird with the 4V Cobra motor but they didn't. That was the reason I went with the '99 Cobra. I still love the looks and ride of my '89 SC but would really like more oomph. Not sure if the 6-speed would be adaptable but I would probably try it. I've done several swaps and would have no hesitation about trying this one. I just finished installing a 393 Windsor and Jeep 5-speed into my '71 Bronco. Wild ride. What do you guys think, should I try it?
