After selling his killer Street Outlaw race car, John Macdonald purchased a 1969 Mustang as a street cruiser project.

However, he also realized that he would need a solid foundation on which to bolt the new top end, so he turned to Chris Holbrook at Holbrook Racing Engines. Catch the rest of the build >>here<<
