Hey guys.

I have purchased a 86 C30 3+3 flatbed. I have a 250 6 and a sm465 that i want to put back in it. I will be driving daily and want to be able to pull a decent load through the hills if I need to. How do i go about building the 250 for torque and dependability? I am looking at the ranger overdrive splitter because I also want to be able to run with traffic on the highway and still get decent mileage.
