Yes, indeed at $4.50 /G here in LA-land we can ill afford carbs today. It should be a straight forward swap. The bigest challenge will be cutting 2" diameter hole in the firewall and running new fuel lines (use new 3/8" soft steel fuel line) for supply.

Your 1 ton probably has 14 bolt FF with 4.11 gears. Depending on tire size your highway engine RPM is between 2500 and 3000 RPM.
