Fast is relative, Hemi vs. Hemi

They probably had - what - 2.76 gears? I knew some Ga. State Patrol officers back in the mid-1970's who claimed their smog 460 Fords would do 160. I was more than a bit skeptical of that claim. Thought it was funny, though, to hear these law officers bench racing just like any hot rodders I ever knew.
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.
