I have a 1997 3.8 NA Thunderbird so far I lve got custom dual exhaust and I got the air intake from super coupe performance. I'm wanting to do a throttle body upgrade. I see BBK has a 56 mm throttle body for the 95-98 3.8 V6 (single port) mustang. I've asked Bill at SC performance and also bbk if it fit the 97 3.8 Thunderbird and they both say it "probably will but not sure about the linkage." Has anyone else with the 3.8 NA tried this? Does anyone the stock throttle body size for the 3.8 NA Thunderbird?
