Prior to the 1964 GTO the displacement limit for GM A-bodied midsize cars was 330 CI. Due to the success of the GTO, it was raised to 400 CI. Olds was first to react to the GTO when sales numbers went from zero to 10,000 in 60 days and decided to jump into the new youth market. To disguise their smaller 330 CI engine they chose a moniker that ignored it: 442 - 4 BBL Carb, 4 Speed, Dual Exhausts.
