The Catalina continued as Pontiac's entry-level full-size automobile with a Buick-built 231 cubic-inch V6 now standard in sedans and coupes (Safari wagons came standard with V8 power) and optional V8s of 301 CID, 350 CID and 400 CID displacements, each Pontiac-built engines and offered in all states except California. The Pontiac 350 was ...
The designation 2+2 was borrowed from European sports car terminology, for a seating arrangement of two in front plus two in the rear. It was designated officially at Pontiac as a "regular performance" model, [2] a thoroughly confusing designation for a vehicle that was clearly intended to be to the Catalina platform what the GTO was to the A-body Lemans: the standard drivetrain was a 2-barrel ...
1975. After the 1974 SD455 was dropped the 1975 Firebird's top performance engine was an 'L78' Pontiac 400 cu in (6.6 L). Pontiac still offered the regular 455 (RPO L75) in its full sized cars, and after a negative public reaction for dropping the 455 engine, it was re-introduced mid-year as an available option for the 1975 Pontiac Trans Am.
The GTO was dropped in 1975, along with the Pontiac 350. The Ventura could be optioned with the Buick 350 V8 instead.

A single overhead camshaft (SOHC) design was introduced by Pontiac in the 1966 model year as the standard engine in the Tempest. Offered also in 1967, the 230 cu in (3.8 L) OHC 6 shared internal dimensions with the overhead valve Chevrolet straight-6 engine it was based on, [citation needed] but had unique cast iron block and head castings ...
The 1975-76 Laguna S-3 featured a more aerodynamic slanted front end but engines were further detuned due to emission requirements and the advent of the catalytic converter, leaving the big 454 V8 unavailable for California cars in 1975 and discontinued altogether for 1976, when the 180 hp (130 kW) small block 400 V8 was the top engine.
During this period, Pontiac's intermediate lineup included the base Le Mans, Le Mans Sport Coupe, GTO (1973 only), Luxury Le Mans (became the Grand Le Mans in 1975), the Euro-styled Grand Am from 1973 through 1975, and on the 1977 Can Am. Body styles were all based on GM's Colonnade design for both sedans and coupes (no convertibles or hardtops ...
