When your goal is to create a world-class pro-touring machine, there can't be any asterisks on its spec sheet. That's why the crew at MASCAR Autobody in Costa Mesa, California started this build with an original G-code 1970 Ford Boss 302 Mustang. A performer from day one, this pony was even factory-equipped with the desirable W-code 4.30 Drag Pack option. And after roughly 2,000 hours of labor, it was transformed into an attention-grabbing pavement pounder that's ready to dominate both the show field and the autocross circuit. Have you been fervidly looking for the perfect muscle car that's as livable as it is lust worthy? Then this awesome Boss pro-tourer is a refreshing cure for your tired eyes!
While this coupe's classic good looks originated in the mind of automotive designer Larry Shinoda, it was the first class professionals at MASCAR that worked double time to ensure those looks present better than ever before. The car's body was stripped to bare metal and completely massaged over the course of 600 hours. A fresh coat of Grabber Green 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. And when all was said and done, this Ford debuted as a fresh twist on a 'can't miss' favorite that puts most common restorations to shame.
For 1970 the Mustang received a smoother body, a less aggressive face, a flat rear valence and a variety of balanced trim tweaks. The idea was to tame looks that some believed were hindering sales and better the car's performance in crucial SCCA Trans Am events. At the leading edge of this super slick Boss, a correct, Mustang-branded grille hangs bright halogen headlights between familiar 'fender fins', a pristine chrome bumper, crystal clear parking lamps and an aggressive chin spoiler. At the top of that grille, a custom fabricated Torino shaker 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. And 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.
Between the aforementioned 'fender fins', a Ken Maisano-built Ford 302 has been fully balanced, completely detailed and stroked to 360 cubic inches. That hot small block utilizes ARP bolts, Clevite bearings, a billet crank, a custom Cam Motion cam, Probe H-beam connecting rods and JE 10.8 to 1 pistons to create mountains of SCCA-winning torque. At the top of the buff mill, a custom air cleaner feeds big Holley carburetors that are tethered to a rare Shelby intake, clean stainless lines and a high quality Edelbrock fuel pump. At the sides of those carburetors, ported DOZE heads conceal Crane rockers, Competition valve springs and Smith Brothers pushrods between Isky lifters and finned Shelby valve covers. At the front of those heads, a familiar points distributor sequences sparks between an MSD ignition system and high quality MSD plug wires. Beneath those wires, ceramic coated headers send charred dinosaurs into a custom-built, three-inch exhaust system. And in front of those headers, a cowled Be Cool radiator circulates water around two Spal puller fans, an Edelbrock water pump, a KRC steering pump, a Powermaster alternator and Cloyes timing components. You'll be happy to know the clean V8 has been sufficiently coated in subdued black paint and properly seated in a gloss black bay. You'll be excited to see items like fresh decals, relocated Moroso breathers, billet pulleys, a correct Autolite rev limiter and TCP truss braces rounding out a trophy worthy engine display. And you'll be thrilled to learn the mean motor burns to a stellar 525 horsepower!
Shine a light under this Boss and a freshly restored undercarriage reveals satin black floors that are speckled with high performance hardware. Behind the stroked 302, a Keisler-supplied Tremec TKO-600 5-speed utilizes a rugged SPEC clutch to pop quick and confident shifts. From there, power is sent to a Total Control Products 9-inch Traction-Lok rear end that's equipped with Strange 4.30 gears; a nod to the car's Drag Pack heritage. Cornering capabilities come courtesy of adjustable VariShock coilovers that are aided by custom-built shock supports, a custom upper pan rod bar, a Chris Alston's Chassisworks 4-link and a roster of TCP suspension products. 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. There's a pair of simple, mandrel-bent pipes that usher spent gases through big Flowmaster mufflers. Chromed and custom widened Magnum 500-style wheels spin 245/45ZR17 BF Goodrich G-Force Super Sports in front of 275/40ZR17 BF Goodrich G-Force Super Sports. And, as with the car's engine bay, many detail items, like a TCP subframe system, Powermaster mini starter and Aeromotive fuel components, mix killer performance with trophy winning aesthetics.
Inside this Ford, a comfortable black interior should make any Mustang fan feel right at home. All the car's soft parts, from its carpet and mats to its headliner and visors, appear new, and the hi-back bucket seats provide plenty of support for spirited driving. From the captain's chair, a familiar Mustang dash mixes straight, crack-free vinyl with tasteful black trim. A nice set of factory gauges keeps tabs on fuel, speed and RPMs while a painted and speed-drilled steering wheel connects the driver to the road via a tilting Ididit column. In the center of the cockpit, a correct factory stereo hangs over an original-looking console that frames small Stewart Warner gauges in front of a chrome Hurst shifter. At the sides of the cabin, attractive door panels hang large pleats behind fresh chrome trim. And behind the passengers, a restored trunk seals a fresh mat beneath a capped and relocated battery.
The sale of this slick fastback includes a few restoration photos, a pile of restoration receipts, a stack of component manuals, notes for the Maisano-built engine and Super Flow 901 dyno results.
It's hard to imagine the automotive world without Ford's Mustang. For almost 50 years, America's original pony car has been admired by racers and purists alike. With its strong drivetrain, capable chassis and nearly universal appeal, this Boss pro-tourer is an excellent mix of old school fun and show-stopping looks. And if you're shopping for a highly desirable classic that incites smiles and turns heads, it's definitely your kind of car!
