Why 3.07's, seems like the Cummins would struggle to get going?

For us it was easier to lower the truck, than raise the Rampage

changed from 245-16 to 215-16 plus spring changes front and rear the 4.10 gear killed the speed/mileage
We like going to Bradenton so put the 3.07 rear in
1st in the 5-speed is no problem to get rolling
engine also has a few fuel mods for more torque,and ported the head/exhaust manifold,

our 92(stock eng/5-speed/3.54, 235-16) seems to struggle more than the 73 climbing hills
