A General Motors corporate edict that took effect with the 1967 model year led Pontiac to discontinue the Tri Power engine options on all of its cars. That year also brought a larger 400 cu in (6.6 L) V8 as the standard engine for Bonneville and other full-sized Pontiacs to replace the previous 389, while the 421 cu in (6.9 L) V8 was replaced by a new 428 cu in (7.0 L) engine that offered as much as 390 horsepower (290 kW). Also beginning in 1967, carburetion was changed. The previous standard 600 cfm Carter square bore four barrel and optional Tri-Power was replaced with the new Quadarajet spread bore carburetor delivering 800 cfm, equivalent to the previous 1966 Tri Power set-up. For 1969, a 360 hp (270 kW) 428 became the standard Bonneville engine, which in turn was replaced for 1970 by an even larger 455 cu in (7.5 L) V8 rated at 370 hp (280 kW).
The 1965-70 GM B platform was the fourth best selling automobile platform in history after the Volkswagen Beetle, Ford Model T, and the Lada Riva.
