The 400 series engines were intended to replace the aging 407ci engine. The 414 and 436 were designed for agricultural applications, while the 466 was designed for light bulldozers and construction equipment.

International started working on what became known as the 300/400 series engines (312ci, 360ci, 414ci, 436ci, and 466ci), and I was on the design and development team. Did you know the first fitment of a 6.9L IDI V-8 into a Ford truck was actually performed at the Hypermax facility? Armed with this knowledge, it’s even easier to see why Hypermax basically had an aftermarket turbocharger system available the day the first diesel-powered Fords graced dealership lots.ĭiesel Army: Did you help design and develop the 466 ci International inline-six, better known as the DT466?

Many of you know or at least suspect that a close tie exists between Hypermax and International.
