We've told you before that the Ford Motor Company plans to celebrate "50 Years of Mustang" by organizing the largest multiday Mustang celebration in history. The series of events will kickstart on April 16 at the Charlotte Motor Speedway and Las Vegas Motor Speedway simultaneously. In anticipation of Charlotte’s celebration of the Mustang’s 50th anniversary, RK Motors today announced it will unveil the “RK527”, an 800-plus horsepower tribute car based on the much-revered 1967 Shelby GT500.
Formed in 2010, RK Motors is a classic car dealer, which currently averages 40 sales per month. Aside from inventory cars, the RK Motors Performance Center has also restored some of the most legendary cars to ever prowl pavement, and those cars have gone on to collect trophies at some of the largest shows in the U.S.

During the special event at the Charlotte Motor Speedway on April 18, RK Motors will take the wraps off a one-of-a-kind Mustang project car, codenamed "RK527", which is powered by a 527 cubic inch Boss Nine all aluminum Jon Kasse-built V8 tower-of-power.

The engine is "de-tuned" to roughly 800 horsepower and features custom heads, Fast XFI ECU port fuel injection, a Billet Specialities drive system, Bryant Billet crankshaft, forged aluminum pistons, 1500CFM throttle body, custom built Good Fab stainless steel headers and 3-inch exhausts with Magnaflow mufflers.

All that fury is put to the wheels via a Tremec T56 six-speed stick shift transmission custom built by D&D Transmission. On the chassis front, the RK527 Shelby Mustang features custom Detroit Speed Alumaframe with adjustable coil-over shocks on the front and QuadraLinks with adjustable coil-overs at the back. Stopping power comes from 6-piston brake calipers with 14-inch and 13-inch cross drilled and slotted rotors from Baer.

The cabin retains the stock '67 Shelby GT500's stock appearance, the only real changes being the heating and air conditioning unit and Stewart Warner Accessory gauges, respectively. The car sits on Vintage HA Series 427 Shelby Wheels and BF Goodrich G-Force Sport Tires.

The vehicle’s debut will also signify RK Motors owner and chairman Rob Kauffman’s plan to drive the RK527 during the upcoming Hot Rod Magazine Power Tour, taking place June 7 to 14.
