RK Motors has a reputation of not only selling but also building some of the coolest and most desirable classic, muscle, and modern performance cars in the world. The RK Performance division is not only responsible for helping owners maintain or upgrade their own cars, but also creates some wild rides with beautiful execution.

RKM recently sent us a teaser video of their RK527 project firing the engine for the first time. This Mustang is sure to create a lot of hype within the classic Mustang community. What RK has done is take a 1967 GT500 tribute car and give it the pro touring treatment making it a serious street and performance machine.

The RK527 utilizes a Detroit Speed Alumaframe complete with coil-over shocks in the front. Detroit Speed quadra-link and coil overs are also used on the rear of the car. The transmission has also been upgraded to a Tremec T-56, but it’s what is in front of that transmission that makes the car really stand out.

To the best of our knowledge, this is the first time anyone has stuffed a big BOSS engine between the fenders of a GT500. This isn’t just any boss engine though, it’s a Kasse 527 cubic inch engine. This beast is stuffed full of a slew of high end, race grade components. that when assembled produce 800 naturally aspirated, fire-breathing horsepower. In the video above the RK Performance crew fire up the beast for the first time, and we have to say it’s music to our ears.

The RK527 is more than just another pretty car with a big engine under the hood. RKM’s own Rob Kauffman, who also owns this car will be taking it on the road this spring and summer. The car will make it’s official public debut at the Mustang 50th Anniversary Celebration in Charlotte, North Carolina. It will also be making the long haul on Hot Rod’s Power Tour this summer as well. We’ll be looking forward to seeing the finished product in just over a month when it’s unveiled to the public.
