Hey guys

ive got a 53 1 ton with the good ol 4 on the floor. I love rowing my own gears, but i also like driving at over 90 Km/h, and not getting 3 mpg. Anyone know of an easy-ish swap to keep a manual trannie, but improve the ratios some? Im already running a 14 bolt out back with 3.73's (maybe 4.10s, never really checked) but i lost all the advantage by putting on modern radials and 16's that were shorter than the original bias plies. What, if any, is the best cheapo option? Or has anyone tried dumping a relatively modern 5 speed behind thier stovebolt? Or, for curiositys sake, has anone gone the full bore route and stuck a brand new T56(or similar) on their favorite 235? What was that like and what did it cost? Any replies are welcome! Thanks!
