I only manage about 70 tops on my 1952 3/4 ton, with M420 4-speed, 4.56 gears, 1:1 final drive, and 32 inch tall tires. And that's buzzing the tach at about 3800 rpm on my 235.
With 3.55 gears, suffice it to say, you should be able to keep up with traffic...on a long straightaway or slight decline.
(235's are very weak motors).
