Pontiac Catalina 2+2 421
Before the GTO created the muscle car segment, Pontiac's performance reputation was built on full-size cars like the Catalina. The 2+2 (pronounced 'two-plus-two') was the performance option package for the Catalina, transforming GM's biggest B-body into a surprisingly quick straight-line performer.
The 2+2 package was first offered in 1964 and continued through 1967. It included Pontiac's largest engines — the 421 cubic inch V8 with either a single 4-barrel (338 hp) or the legendary Tri-Power triple-carburetor setup (376 hp). The 421 Tri-Power Catalina was one of the fastest full-size cars of the 1960s.
Despite its enormous size (over 17 feet long on a 121-inch wheelbase), the Catalina 2+2 could run mid-14-second quarter miles with the Tri-Power engine. Its weight actually helped traction off the line, and the 421's massive torque made it deceptively quick in rolling starts.
The 2+2 was a separate model for 1965-66, with its own grille, emblems, bucket seats, console, and heavy-duty suspension. In 1967 it reverted to an option package. These cars represent the earlier, pre-GTO era of Pontiac performance — when the company earned its 'Excitement Division' reputation by putting big engines in big cars.
The Catalina 2+2 is a relatively overlooked collectible that offers tremendous value. While GTO and Firebird prices have soared, a genuine 421 Tri-Power Catalina can still be found for a fraction of the cost while delivering equally impressive performance.
The Catalina 2+2 is undervalued compared to equivalent GTO and Firebird models. Tri-Power cars are the most desirable. Full-size Pontiacs are rust-prone in the same areas as other GM B-bodies: rocker panels, trunk floor, quarter panels. Parts are shared with other GM full-size cars, making restoration feasible. The 421 Tri-Power is complex — synchronizing three carburetors requires experience. Verify 2+2 equipment via PHS documentation.
1965: 11,519 (2+2 as separate model). 1966: 6,383. 1967: 1,768 (option package only). Tri-Power cars are a fraction of total production. The 421 engine was replaced by the 428 for 1967. After 1967, the performance full-size concept faded as insurance companies began surcharging big-engine cars.
