Frame Off Built Mustang Boss 302 5 Speed Pro Touring

The pro-touring scene has gotten big enough that there are divisions starting to emerge. One side builds cars that look great but don't actually perform while the other side is more focused on pulling 1g on the skid pad than overall usability or comfort. There's nothing wrong with either but cars like this 1969 Mustang Boss 302 are reminders that you don't have to choose a side at all. Nicknamed “Mr. Nasty” this blue oval is a $120k build that plants a 656hp V8 paired with a Tremec five-speed in the center of an authentic G-code Boss 302. Best of all, it's a completely livable and functional car with paint and body work that would make most MCA cars quiver in their Polyglas boots. If you're ready for a pro-touring car with absolutely no asterisks, gimmicks, or excuses, get to know this killer '69 Boss 302.

While this Mustang is an authentic Boss 302, the first class professionals at MASCAR Auto Body in Costa Mesa, CA decided to work double time to transform it into something much better than 40 year old factory fodder. The car's body was stripped to bare metal and completely massaged over the course of several hundred hours. A fresh coat of Acapulco Blue two-stage was accented with classic Boss war paint. Panel fit and finish work was refined to faultless levels, creating clear reflections from a profile that displays a notable absence of flaws. When all was said and done, this Ford debuted as a fresh twist on a 'can't miss' favorite, putting most common restorations to shame.

A closer look only strengthens the car's glowing first impression. At the leading edge of this super slick Boss, a correct Mustang-branded grille hangs bright halogen headlights, a pristine chrome bumper, crystal clear parking lamps, and an aggressive chin spoiler. At the top of that grille, a smooth hood complete with a built-in tachometer leads the eye to like-new glass that's framed by spotless stainless wipers, correct sport mirrors and straight, polished trim. At the sides of that glass, re-fashioned fenders combine with chrome-trimmed marker lights and traditional Ford door handles to provide an aggressive, yet finished appearance. At the back of the car, a correct black valence anchors an ornate fuel filler and segmented tail lights between a large decklid spoiler, a fresh “MUSTANG” script, a second pristine bumper and wide-set reverse lamps. Look closely above the passenger side taillight and you'll see a small “Mr. Nasty” decal, reminding onlookers this isn't your run-of-the-mill Mustang.

Nothing leaves Ken Maisano's shop underpowered and this Boss 302 is definitely no exception. It features a hot Ford SVO blocks that's been balanced, blueprinted, and stroked to 365ci. The mill starts with a new four-bolt main Ford Racing M-6010-BOSS302 block filled with high-end pieces like a SCAT 4340 forged steel crank and a Cam Motion mechanical roller cam. Up top, a 950cfm Holley carburetor tops a painted aluminum intake manifold with aluminum heads at either side. According to the dyno sheet, the engine puts out an impressive 661hp and 468lb-ft of torque, finding its sweet spot somewhere around 7,250rpm. The front of the engine spins a Jones Racing Products accessory drive with an alternator and power steering pump while the water pump teams up with an aluminum radiator and a pair of SPAL electric fans to keep the 302 cool. The carb draws air through a slick Trans-Am-style sheet metal intake while, further left, a pair of external breathers continue the track friendly look. Despite the modified appearance, there are some great vintage pieces here as well including the date coded Boss oil cooler and the Autolite governor mounted to the driver side inner fender well. The engine sound great, runs strong, and its surroundings are impeccable – truly the best of all worlds.

Shine a light under this Boss and a pristine undercarriage reveals satin black floors that are speckled with high-performance hardware. Behind the built 302, a Keisler-supplied Tremec TKO600 five-speed utilizes carbon fiber blocking rings for high-rev shifts. From there, power is sent to a Ford 9-inch rear axle tucked into one of TCP's stout FAB9 housings. Cornering capabilities come courtesy of a full Total Control Products with VariShock coilovers. The front utilizes stout control arms while the rear is supported by a g-Bar four-link system. A power rack and pinion setup keeps steering effort minimal while electrically-assisted Wilwood 12-inch disc brakes ensure the car stops as well as it goes. Chromed and custom widened Magnum 500-style wheels spin BF Goodrich G-Force Super Sports in sizes 245/45ZR17 and 275/40ZR17. As with the car's engine bay, many detail items, like the tubular subframe system, Powermaster mini starter and coated exhaust system with Dynomax mufflers, mix killer performance with trophy winning aesthetics.

Inside this Ford, a comfortable black interior should make any Mustang fan feel right at home. The door panels remain in stock configuration but, step over the Ford-badged door sill plates, and you'll find that virtually everything else has been upgraded in some fashion. The seats are thoroughly modern pieces perfect for bouts of spirited driving. Wrapped in black leather, they match the overall motif and blend in surprisingly well. Between the buckets, the leather-topped center console offers storage space and room for the shifter as well as a pair of Stewart Warner gauges that keep tabs on water temperature and oil pressure. Above, the factory heater controls keep their spot as does a Philco AM/FM stereo with wood grain accents. The passenger gets a view of an analog clock surrounded by wood grain applique while the driver gets a set of Ford gauges that keep tabs on speed, fuel levels, amps, and temperature from their deep round housings. In front of those gauges, a leather-wrapped steering wheel tops a tilt column, offering control of the front wheels. Take a look in the trunk and you'll find nothing but a clean and simple space with the battery tucked in the left corner.

The sale of this slick Boss 302 includes plenty of historical documentation including an Eminger invoice, owners manual, original warranty cards, a Marti report, and Boss 302 registry documents. There are also restoration receipts, component manuals, a detailed engine build sheet, and a dyno sheet to confirm those killer numbers.

There are a lot of Boss 302's out there and some are even restored to this level visually but one ride is all it takes to confirm this is a very different kind of Mustang. With its killer Maisano-built 302, Tremec five-speed, and even-keeled suspension, this is a car you can push through the corners all day without feeling out of control. Best of all, you can bring a friend and cruise in all-day comfort. If you want a no-compromises pro-touring Mustang, this Boss 302 is the one for you!
