I have nothing against Detroits. I have one in my yard truck. When I wrecked my 550 in 1968, I looked real close at an 860 with a 671, but I was hauling a lot of grain in those days and we used to gross 100,000 because Texas really didn't enforce their weight laws in those days. A discovered that a Cummins pulled the hills with a whole lot less shifting. I still run Cummins hauling bulk commodities. I like to make jokes about Detroits though. Central Freight out of Waco, TX ran all GMC with Detroits in the 50's and 60's. Every truck stop s___house poet used to write, "If speed kills, Central drivers should live forever." and "Detroits make very good stationary engines. Put one in a truck and it becomes almost stationary." But you must remember I am from a generation of drivers who took pride in their choice of trucks and made fun of the rest. We spent hours in truck stops bragging about "how fast them trucks would go". There is no way I could make a living with any truck that was built in the 50's. I admit my old trucks are nothing more than toys now, and kids have always like different toys.
