Stock Turbo, 1,200 HP!Īlong with the engine, the factory 60mm IHI turbocharger is still aboard Buddy’s LB7. The common-rail V-8’s fuel system has been upgraded in the form of a 12mm stroker CP3 and 200-percent over injectors, with Danville Performance fine-tuning the ECM. Even the factory head bolts are still intact! But that doesn’t stop Buddy from making the Duramax turn 4,500 rpm or belt out 1,200 hp. And being that his truck has been as quick as 5.73 in the past, he lays claim to the fastest stock engine LB7 Duramax in the world.

Unbelievably, Buddy campaigns a bone-stock, 300,000-mile LB7 Duramax. Instead, a King Pin Dana 60 with leaf springs is present, while a 14-bolt AAM 10.5-inch rear axle resides out back. And in addition to its lack of an Allison, the front IFS is gone, too. Buddy regularly cuts 1.31 to 1.33-second 60-foots thanks in part to a four-link rear suspension with coil over shocks and a Twisted Diesel 4L80E transmission he tunes himself using a Powertrain Control Solutions TCM-2800.

The 4,500-pound GMC is nothing like some of the full tube chassis builds in 5.90, but the setup works extremely well. Like something out of a Mad Max film, Buddy Callaway’s ’03 GMC Sierra 2500 shortbed looks beat up and thrown together-but it’s one of the most consistent trucks in the class. Each build is different, but on race day their goals are the same: running the number. It’s a class without weight restrictions, turbo limits or any one-size-fits-all approach-and with 19 racers following the ODSS race schedule in 2021 it’s downright entertaining to watch.īelow, you’ll get a glimpse of what you’re in for when you take in a 5.90 race: two top-tier GM’s-both of which already have a win under their belt so far this season-and a consistent, third-gen Cummins that’s currently Second Place in points.

Within the ranks of 5.90, there are a host of Duramax-powered GM’s and even Power Stroke-propelled Fords.

And unlike many other diesel racing classes, it isn’t primarily dominated by Cummins power plants. It might be index racing, but it’s very close and extremely fast. The category has grown in leaps and bounds since its debut just a few short years ago and the competition is second-to-none.

When the decision makers behind the Outlaw Diesel Super Series decided to introduce the 5.90 Index class, they did their organization a huge favor.
