1965 Hi-Po Engine vs. Shelby 289 Short-Block - Mustang Tech

Shelby Rated The GT350'S Cobra 289 At 35 Hp More Than Ford's 289 Hi-Po. Was That Accurate, Or Was It Snake Oil?Looking back at Ford's history during the mid 1960s, you would be hard pressed not to read about Carroll Shelby. Although he is perhaps best known for gracing the world with the Cobra, one of the most powerful and legendary automobiles in history, he also had a hand in many other success stories, like beating Ferrari with the Cobra Daytona Coupe. He was also partly responsible for the tremendous success of Ford's own GT40 project, winning the LeMans 24-hour endurance race two years in a row.inline_mediumwraptextrightRecreating a Hi-Po or Shelby 289 short-block was not terribly difficult. The Demon Engines' 289 was built from a late-model 5.0L block stuffed with a 289 (2.87-inch) crank, rods, and forged flat-top pistons from Probe Racing. The forged slugs featured four valve reliefs to duplicate the factory Hi-Po pistons and static compression ratio.26840705/techarticles/mump_1003_1965_hi_po_engine_versus_shelby_289_shor t_blockmump_1003_02_+engine_dyno_test+demon_289_en gine.jpgTrue
