I've been up to 65 in mine (216 was on its way out anyway
), it still handles fine (I have radial tires), but you need to be careful about hard braking making it squirrly. I am going to put a swaybar on it and eventually disc brakes. My front suspension has been completely gone over, though, with new shocks, bushings, wheel bearings, shackles, king pins, and adjusted steering box. I wouldn't drive it on the highway without that. I like to not hit things.
