Ford Racing turns 125 this year, and its SEMA birthday car is a 1966 Mustang Fastback. The best part is not the paint: its engine has a twin in Ford's own parts catalog.
The short answer
The R125 is a heritage-inspired restomod of a 1966 Mustang Fastback that Ford Racing showed at SEMA 2026. It runs a 347-cubic-inch crate engine rated at 360 hp and 400 lb-ft, through a Tremec TKX-600 five-speed. Ford built it for show, to show off Ford Racing Parts, so Gear Patrol notes you'd have to recreate it yourself.
What is the Ford Racing R125 Mustang?
A first-generation Mustang dressed for the anniversary. Gear Patrol describes a black, gold and red scheme, a nod to the livery of Ford's IMSA GTD Pro race cars.
Ford's Matthew Simpson, Executive Director of Ford Customization, kept the pitch modest in Ford's own post: "The R125 is one interpretation of what a 1966 Mustang can become."
What engine does the R125 use?
A 347-cubic-inch small-block crate engine. Ford says it pairs a Ford Racing Boss block with aluminum heads and Edelbrock Pro-Flo fuel injection. The valve covers come in two pieces, with swappable tops, captured O-ring seals and built-in looms for the plug wires.
Can you buy the R125's parts?
Ford says the parts are offered through Ford Racing Parts, and Gear Patrol says buyers would recreate the car that way. The catalog lists an EFI crate engine with the same headline numbers:
| Spec | R125 (Ford's SEMA release) | X2347 EFI Dressed crate engine |
|---|---|---|
| Displacement | 347 cu in | 347 cu in |
| Power | 360 hp | 360 hp |
| Torque | 400 lb-ft | 400 lb-ft |
| Block | Ford Racing Boss | Boss 302, 8.2-inch deck |
| Fuel injection | Edelbrock Pro-Flo | Edelbrock Pro-Flo 4 XT |
| Retail price | not given | $13,750 |
Ford doesn't say the R125 uses that exact part, but the specs match. The catalog engine runs on premium pump gas and tops out at a recommended 6,000 rpm. One catch: Ford Racing Parts lists it for competition or off-highway use only, not for a car driven on public roads.
Why the TKX five-speed?
Ford says the Tremec TKX-600 shifts smoother and is more durable than the older Tremec TKO. Hagerty reports that Ford says it fits with only small changes to the floor pan, and that the build is aimed at smaller budgets.
Why 125 years?
The count goes back to October 10, 1901, when Henry Ford won a ten-lap race at the Grosse Pointe Race Track. His Sweepstakes car had an estimated 26 hp, and he passed the favorite, Alexander Winton. The Henry Ford museum says the win helped him find backers, and Ford Motor Company followed in 1903. Ford says Ford Racing now competes in 36 major championships around the world.
On the street
At a show, the black, gold and red paint gives it away. If you are planning a first-gen Fastback build, the useful bit is the parts list. Read the crate engine's off-highway listing before you plan to register the car.
