Probably hardly anyone has even heard of this movie, and that's all right, because the only people who would care about it are truckers and hot rodders. As far as the plot goes, let's just say there's a secret government operation here, subject to terrorists and internal corruption. Forrest Tucker was a man many people today are not familiar with, but he had a lot of roles and was a common name. And then we have John Shepherd, who is not a familiar name but is worth checking out. His character drag races a Chevy pickup, apparently one of the fastest in existence, and it seems the girls flock to him two at a time. There's also a scene with the "Cotton-eyed Joe." Anyway, Forrest and John are trucking plutonium in a high-tech customized semi with the Chevy on board, just in case they need it. The Kenworth conventional tractor has a 8V-92 Detroit, apparently the best powerplant for this mission. Now for the best part of this whole movie: Where White Line Fever gives you a truck tractor jumping through the air, Thunder Run gives you a whole semi!! Later they have to abandon the rig and use the Chevy to escape from a 12V-71 Detroit-equipped Kenworth cabover which gets wrecked. Anyway, they get like $250,000 for the run, and John asks Forrest what they're going to spend it on, and, like a real man, Forrest says "On anything we damn well please!"
