Jayden's High Performance Big Cam

Jayden's High Performance Big Cam

What an amazing industry the diesel engine and trucking business is. You never know who is going to call, stop in, what they know and what they are capable of.  About 1 month ago a gentlemen called me and mentioned he purchased an older Superliner Mack powered by a Big Cam 350 Cummins.  He knew nothing about the truck. However, he wanted it to run well and would work it at times, but the main use was to haul his 2 pulling Chevrolet pickup trucks to the truck pulls.  He then told me his 14-year-old daughter pulls one of them...

Drive What You Like

Drive what you like. Many times I get phone calls from owner-operators asking me what truck they should buy.  My answer is “What is your favorite truck, what would be your dream truck.”  Many of us still prefer the long hood trucks, 359, 379, 389 Peterbilts, W900 Kenworths, Western Stars, and the Freightliner Classic.  Yes, the fuel mileage is about ½  mile per gallon less than an aerodynamic truck, and that mileage can be made up by driving via the turbo boost gauge and slowing down slightly. However, if you’re like me, you want to love the truck, car, motorcycle,...

The Good Ol' Series 60 Detroit

The Good Ol' Series 60 Detroit

Even though the Detroit Diesel Series 60 was discontinued in 2011, it’s still one of the most common engines for Class 8 trucks. Some may not know about the fascinating story behind these engines. At the onset of WWII General Motors created the GM Diesel Division in 1938 to build engines that would support the war effort. Their first engine, the Series 71 2-stroke engine was used in tanks, generators, and construction equipment during the Second World War. After the war, Detroit kept producing the Series 71 along with the new Series 53 for on highway use. Detroit’s engines were...

Differential Gear Ratios

Differential Gear Ratios

Differential gear ratios; there is a lot of confusion in the trucking industry about what is the best gear ratio for pulling power, fuel mileage, and a good cruising speed.  This article will pertain to the over the road semi truck, NOT heavy haul, or vocational local trucking. To pick the right rear gears you must know the peak torque RPM of your engine, the ideal cruising RPM, and the speed you mostly drive on the interstates.  Today almost all transmissions are double overdrive which is a .73 final drive gear.  The standard 13 and 18 speed transmissions are all...
