A yellow 1970 Ford Mustang with a white roof and matching white interior would already stand out in a field of restored pony cars. This one adds years of outdoor storage, failing paint, a non-running engine, dead brakes, and a drivetrain description that raises a much bigger question.
The car appears to be a 1970 Mach 1, yet the engine under the hood is described as a 351 Cobra Jet. That combination is unusual because Ford did not offer the 351 Cobra Jet in the Mustang for the 1970 model year.
Scott, host of the Always More To Do YouTube channel, recently pulled the Mustang out after a long period of sitting and began by giving the exterior a much-needed cleaning. Mechanical repairs are still ahead, along with a closer look at the car’s history and exactly what has happened beneath the hood.
At the moment, this Mustang is part restoration project and part detective story. Its unusual colors, neglected condition, and questionable engine identity make it considerably harder to categorize than the average barn-find Mach 1.
The 351 Cobra Jet Doesn’t Quite Add Up
Scott introduces the Mustang as a 1970 351 Cobra Jet, and there is indeed a 351 Cleveland-family engine sitting under the hood. The problem is that Ford didn’t introduce the 351 Cobra Jet Mustang until the following model year.
In 1970, Cobra Jet Mustangs were associated with the 428 cubic-inch big-block, while 351-powered cars could be ordered with Cleveland engines in other specifications. That leaves us with a few possibilities, including an engine swap, a later 351 Cobra Jet installation, or simply a mistaken description of an original 351 Cleveland.
Without a Marti Report, engine codes, or other documentation, the exact answer isn’t yet known. That uncertainty is one of the more interesting parts of the project, especially if it turns out the car retains much of its original drivetrain.
Years Under A Tree Left Their Mark
The Mustang had apparently spent years sitting beneath or near a cedar tree, and the exterior showed it. Dirt, organic debris, grime, and stains had collected around the trim, spoiler, windows, and body seams.
Scott began with a pressure wash before moving to a hand wash and clay bar. Compound, polish, and wax followed, pulling a surprising amount of shine back out of the yellow paint despite significant deterioration beneath the surface.
The improvement is largely cosmetic rather than permanent. Scott believes rust is developing underneath parts of the paint, meaning a complete strip and repaint will eventually be needed if the body is going to be properly restored.
The White Interior Has Problems Of Its Own
The cabin is nearly as unusual as the exterior, with extensive white upholstery contrasting against the yellow body and white roof treatment. Without documentation, it’s impossible to tell whether that entire color combination is factory-original.
Time hasn’t been particularly kind to the interior either. Over the years, water has entered the car, so the seats need attention, and portions of the cabin show visible moisture damage.
The exterior roof treatment also raises questions because a white roof on a Mach 1 SportsRoof is far from typical. It may be a later customization, although the trim separating the colors gives the conversion a surprisingly deliberate appearance.
The Mustang Doesn’t Run Or Stop Yet
Cleaning the body was only the first stage. Scott says the engine currently doesn’t run, although he believes it may only need relatively minor work before an attempt can be made to bring it back to life.
Opening the hood provided one obvious clue about how long the Mustang has been dormant: a dirt dauber nest was sitting around the carburetor. The engine itself appears complete enough to provide a solid starting point, but it hasn’t yet undergone the mechanical work needed to determine its condition.
The brakes also aren’t functioning, so getting the Mustang safely moving under its own power will require considerably more work than the exterior cleanup.
Its Real Identity Is Still The Best Part
From a distance, the transformation already makes the Mustang look dramatically better than it did when it arrived. Up close, however, the tired paint, damaged interior, and years of neglect make clear that this is still a major project.
The bigger question is what the car actually is beneath those layers of history. If future documentation confirms its original engine, trim, and color combination, this strange yellow-and-white Mach 1 could become even more interesting than it already looks.
Until then, the contradictory “1970 351 Cobra Jet” description is a mystery, and for a Mustang that has spent years hiding under a tree, it sure has a lot of explaining to do.
