521-Powered 1969 Ford Mustang Mach 1 5-Speed

This 1969 Ford Mustang Mach 1 was rebuilt and modified in 2018 by Sic Chops of Cave Creek, Arizona, including the installation of a boxed Roadster Shop Fast Track chassis and a repaint in Avalanche Gray. Power is supplied by a 521ci V8 built by Jon Kaase Racing Engines that features “Boss Nine” aluminum cylinder heads with individual throttle bodies, an aluminum intake manifold, and a Comp Cams camshaft. A Tremec five-speed manual transmission has also been installed, and additional equipment includes a Strange Engineering 9″ rear axle, 18″ and 19″ Colorado Custom billet aluminum wheels, Baer four wheel disc brakes with cross-drilled rotors, power-assisted steering, C6 Corvette-based suspension, Penske double-adjustable coilovers, and a dual exhaust system with Magnaflow mufflers. The interior was reupholstered with red leather and fitted with a Colorado Customs steering wheel, Dakota Digital instrumentation, a 10-speaker Kicker sound system with Bluetooth connectivity, Vintage Air climate control, and a Passport radar detector. This modified Mach 1 is now offered on dealer consignment in Arizona with two SEMA awards, an issue of Hemmings Muscle Machines in which the car is featured, and a clean Montana title.

The body was stripped to bare metal, repainted in Avalanche Gray, and affixed to a Roadster Shop Fast Track boxed frame during the build process. Exterior features include a hood scoop, a black-finished brass grille surround and window trim, driving lights, hood pins, Boss 529 graphics, twin side mirrors, and black bumpers. The front spoiler is bent along the lower-left side.

Black-finished 18×9″ and 19×12″ Colorado Custom billet aluminum wheels feature Mustang-branded center caps and are mounted with Nitto Invo tires measuring 275/30 up front and 345/25 out back. Braking is handled by Baer four-wheel discs equipped with 14″ cross-drilled rotors, six-piston calipers, and stainless steel lines. Additional features includes a Woodward power-assisted steering rack, 1.25″ front and rear sway bars, and C6 Corvette-based front and rear suspension equipped with Penske double-adjustable coilovers.

The cabin was overhauled by Ron Mangus Hot Rod Interiors of Yucaipa, California. The high-back front bucket seats were fitted with additional padding and mounted lower to the floor, and the cabin was re-trimmed with red leather upholstery. The floors are lined with black carpeting while gray birch trim adorns the dash, center console, and door panels. Additional features include a Philco push-button radio, a 10-speaker Kicker sound system with Bluetooth connectivity, Vintage Air climate control, and a cue-ball shift knob. A Passport radar detector is housed in a custom housing stationed below the gauges.

The leather-wrapped Colorado Customs steering wheel is affixed to an ididit adjustable column and frames Dakota Digital instrumentation consisting of a 120-mph speedometer, an 8k-rpm tachometer, and digital auxiliary gauges. The digital odometer shows 214 miles, and total chassis mileage is unknown.

The 521ci V8 was built in 2018 by Jon Kaase Racing Engines of Winder, Georgia using a Ford Racing SVO block and “Boss Nine” aluminum cylinder heads. Equipment includes 58mm individual throttle bodies, an aluminum stack-injected intake manifold, a custom-fabricated oil pan, a Comp Cams hydraulic roller camshaft, diamond-forged pistons, Lunati Power H-beam connecting rods, and an MSD distributor. The custom dual exhaust system features 2″ headers, 3″ cross-over piping, and Magnaflow mufflers.

The 2018 dyno test sheet indicates peak output of approximately 851 horsepower and 723 lb-ft of torque.

The Tremec TKO 600 five-speed manual transmission has been fitted with a Ram Clutches 11″ clutch and sends power to the rear wheels through a Strange Engineering 9″ rear axle with 3.73:1 gearing and 31-spline axles.

The car received Ford’s Special Recognition Award for Outstanding Achievement in Design at the 2019 SEMA show along with a Masters of Motors award from JE Pistons at the same event. The car was featured on the cover of the September 2021 issue of Hemmings Muscle Machines, and an article from the magazine describing the build process is viewable in the gallery.
