A 1970's LTD at 160? Float isnt the word you would use - IF it could get anywhere near that. In 1983 I bought my uncles 77 Ford unmarked Chiefs unit when he retired. The 460 was kinda soft getting to 75 mph, but sounded great. Still had the department issue Chapparal high speed tires on it. I would love to tell you top speed, but I only saw 120 on the certified speedo. More than once I accidentally went past a cop parked on the interstate with no repercussions. You would not be that lucky today, they know who's who.
