1969 Ford Mustang Boss 429 Restomod — Kaase-Built 505ci, Pro-Touring Restoration

Here is a Boss 429 tribute built without compromise, presented exactly the way discerning collectors dream of finding one — a real 351 Mach 1 transformed through a comprehensive 2017–2020 restoration into a modern, road-devouring pro-touring machine. Few names carry the mystique of the Boss 429, and this build honors that legend while delivering the reliability, handling, and refinement today’s enthusiasts demand. Beneath that unmistakable fastback silhouette lives a monstrous 505ci V8 assembled by the legendary Jon Kaase Racing Engines, backed by a modern Tremec five-speed and a fully sorted independent chassis. You can simply get in it and go. Slide behind the Dakota Digital gauges, grip the shifter, and imagine adding this exquisite, purpose-built Mustang to your own collection.
