Does it get any crazier? Perhaps it's about as awesome as it gets! We've embarked on a journey to build a customer, a '67 Mustang. His only stipulation is that it make big horses, so with a spare set of Boss 429 shock towers and an engine for the hole, we're throwing a NASCAR Boss 429 engine into it. It'll make a bucket-load of horsepower and torque, but most of all, will look absolutely awesome in the engine bay of this '67! Watch this space as it all starts and comes together.
