The machines and infrastructure it takes to successfully use those manufacturing methods have been around for a couple decades, but remain typically in the high-tech and OEM realm. They’ve been used to produce concept cars, but to our knowledge the Harbinger is the first muscle car to rely heavily upon them, and it’s definitely the first one available with these technologies on a production level. And according to Agent 47, it’s an on-going experiment. They plan to continue using this car, and Forecast3D’s machines, to develop and design more products for ’69-70 Mustangs, and earlier ones down the road.

Does that mean this machine was built by machines? Not at all. Computers aren’t artists or innovators, so just like any hot rod shop there was a highly talented crew, including Josh Tieman, Roger George, Lathe Sailor, Mike Winston, and Bryan Rogers handling the design work, fabrication, and wrenching. They just had some more advanced equipment on their side. The result is what may be the ultimate off-the-shelf, call-up-and-order-it, competition muscle car roller. You don’t have to take our word for it, though. Agent 47 has had numerous test sessions dialing in the suspension and driveline, and has so far run a 1:30 lap at Willow Springs. Check out the videos on and Beyond that, there’s serious discussion about putting the Harbinger in the American Iron or American V-8 Supercar Series.

Traditional hot rod building isn’t going away, but we are getting a taste of what cutting-edge technology will bring to build better rods. If indeed this Harbinger car is an omen that portends of things to come in the hot rodding hobby, we’ve got high expectations for the future!
