Big tires, overdrives, or a 5 speed are options.
Personally like the H55F option and taller tires. Lower first on the H55F helps make up the loss for taller tires on the low end. The 74 still has the skinnier high range gears. Low range gear while wider were not as low in low range as the three speed case. H55F uses a split transfer case which is stronger and quietier. Also has options for low range gearing. Taller tires and higher 3.70:1 diff ring and pinion in the diffs both suffer on the low end. If your only concerned with on pavement driving those are fine. If I wanted a vehicle I didn't plan using off road a 70s Land Cruiser would not be it.
