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




Won't be hauling a boat

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
