About the Magazine
The October issue of Diesel World captures the sights, sounds, and excitement of the 2023 Ultimate Callout Challenge, including exclusive coverage of the drag races, dyno competitions, sled pulls, and more! We also feature a beefed-up ’70 GMC K15 as it gets new life on the track, a ’68 International Loadstar that goes totally against the grain, and Aaron Brose’s dragstrip destroyer: a 900hp shortbed. But that’s not all! We check out David Keyser’s daily-driven OBS FORD F-250, and our Truck of the Month—Chris Voorheis’ ground pounder that’s ready to race!
