Your numbers are correct. I had a 86' 5th ave and it was a good ride. Had a lock up converter and it would cruise nicely at 90. Not that I drive that fast, but at 60 and not paying attention it would sneak up to 90 at times. Only complaint was the interior was a little inferior due to all the plastic items and cloth panels that would fall apart. Not a race car, but a good cruiser.
