2. 1965 Pontiac 2+2
As far as classic muscle cars go, the ’65-’67 GTO is remembered to be about as big as they came. But with the success of the GTO, Pontiac wanted to take its go-fast formula to an even bigger car, which became the ’65-’67 2+2.
Based on the full-size Catalina two-door, the 2+2 had its own unique 338-horsepower 421-cubic-inch V8, and in High Output guise, power jumped to 376 ponies, which when tuned right could rocket from zero to 60 in a mind-bending 3.9 seconds. Bigger, plusher, and often faster than its smaller stablemate, the 2+2 deserves a lot more love from speed freaks.
