Blast From the Past 359

Blast From the Past 359

A BLAST FROM THE PAST - Last week we had a 359 Pete in our shop with a Big Cam Cummins 700+ horsepower engine we built years ago. This engine had our High Lift Camshaft and MVT (mechanical variable timing) system so there is no smoke at idle and the timing retards at high power to increase the life of the pistons. The pistons are a high strength Cummins piston that were ceramic and Teflon coated, which we still do.  It also has our performance turbocharger and oversized gear pump on the fuel pump which measured 1.25 inches vs the...

The first two paragraphs of this article were written by our lead Electrical Engineer Ethan, and they pertain to the emissions systems used on the Detroit DD15 and DD13 exhaust systems, which are commonly referred to as “One Box”...

Rebuilding Older Trucks

Rebuilding Older Trucks

Many of us who have been in the trucking industry all our lives, and even some younger people, have a fascination for antique trucks.  There’s something special about the rebuilding of “Old Iron,” a Class 8 truck from the mid 1970’s and older. This article will be about a commonly overlooked  problem when installing a newer diesel engine into an older truck. Please keep in mind that the older low horsepower and smaller cubic inch engines do not require a lot of fresh air measured in CFM (cubic feet of air per minute).  The small cam Cummins engines that were...
