1965 Pontiac Catalina

As an elongated low-riding model, the 1965 Pontiac Catalina offered many options from color and performance to engine upgrades. The full size two-door hardtop and convertible versions of the Catalina had the ability to use Pontiac’s 421 cid engine, despite the infamous General Motors ban on engines larger than 400 cid. The ban was in effect for intermediate vehicles, allowing the Catalina to skirt the rule because of its status as a full-size vehicle. This fastback further impressed with the addition of the “2+2” package option, which included the bigger engine among a handful of other upgrades. This option was phased out only 2 years later, in 1967, because it simply didn’t achieve the overwhelming successes of the GTO.
