what type of fuel injection did pontiac bonneville have in 1966
The early GM fuel injection system was developed for the Corvette. I don't know if the Bonneville came that way from the factory or if someone could have swapped engines/fuel systems later. It is/was possible that it was ordered that way because if you knew the part numbers, you could order cars with anything. --- I had a friend who's uncle ordered a Olds Vista Cruiser wagon with all the 442 equipment one year before the 442 became a trim package. It was a V8, four speed, dual exhaust wagon with the small windows around the roof. He traded it in for a '66 Goat. Life was good in those days. I knew two people who had Shelby Mustangs (I got to drive one of them around all weekend) and three people who had 327 four speed Chevy II's.
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.
