This engine package pays tribute to the 427 Side Oiler which dominated sports car racing, Nascar, NHRA, and winning at Le Mans in the Ford GT40 in 1966. Based on a Dart Windsor SHP block, this package is the ultimate big cubic inch small block. Even with its abundant power throughout the entire rev range, it still remains street friendly and reliable. Whether you are building a Cobra, GT40 or Mustang, this is your opportunity to power it with an engine that has proven itself to be the most legendary engine in American racing history.
