Actual output was well over horsepower kW. Some people have claimed it to produce or more horsepower, citing extensive testing to prove the results, though nothing has been actually proven. However, it is very easy to coax such power out of the semi-hemi engine due to it being factory de-tuned for street-ability purposes.

These horsepower claims have been proven from many dynamometer test results over the years with factory stock engines; some rebuilt to factory specs, and others pulled directly from the cars themselves immediately after purchase, though specific output tends to vary per engine due to testing parameters. The Drag Pack option from Ford at the time which was a normal SCJ and not the Boss version which made more power had horsepower kW , which was quite impressive for the time, however it should be noted that these ratings were strictly engine crank horsepower, and not actual wheel horsepower figures.

The manufacturers and dealers only listed hp kW because of legal issues and rising insurance costs so customers would be lured into buying these cars without the stiff fees from an insurance company, though no manufacturer has ever stated this to be true, assumingly so to prevent possible lawsuits.

The new, revised, front apron assemblies that accepted the large Boss engine had been installed by the Rouge plant as the base vehicles were being built; this produced a stronger and cleaner front structure. The reworked front fenders were also installed at the Rouge plant.

This was the first Mustang ever fitted with a rear sway bar, and so it handled much better than the other large engine Mustangs of the time, making it a much more capable track car. It came fitted with an 8,rpm tachometer, and AM only radio.

Other features included a front spoiler that was shallower than the Boss spoiler, color-keyed dual racing mirrors, and an engine oil cooler. It was also equipped with a 3. Supposedly, the manufacturers and dealers only listed hp kW because of legal issues and rising insurance costs so customers would be lured into buying these cars without the stiff fees from an insurance company, though no manufacturer has ever stated this to be true.
