hmmm my uncle has a 97 T-Bird with the 4.6 and he was running mid 15's in the 1/4 with the only mod being a 2 1/2" cat-back exhaust. So I believe this guys numbers were pulled from thin air. He would be lucky to get low 16's in the 1/4 and maybe mid to high 7 sec 0-60 times. It's still faster than a Zetec tour, but it would be a fun race, watching a big V8 powered XR7 barely beating a 4 banger in the 1/4... Just my thoughts
