'88 T Bird - LX or Sport?? Reply #15 – December 19, 2006, 03:44:02 PM Quote from: misteramx;119284Thanks for the welcome, are you planning on stepping up to an 8.8? Oh and yes, I do have the buttstuffog gauges. Wonder if you can still get the 140 mph motorsport speedometer for these? You know, I have been reading a lot of threads on the HO conversion and I wonder...wouldn't it be just as easy to pull a 5.0 from an '88 Mustang or Lincoln LSC. I mean the entire motor and computer? Or am I missing something here?Actually it's easier to just swap the motors. All you have to do is plug in a Mustang or MK VII speed density computer with the HO motor and you're all set to go.
