not be ordered in a Rebel (or later Classic) through 1964. For 1965 and 1966 the 287 and 327 were both available in the Classic and Ambassador. The AMC 327 was sold to Kaiser-Jeep from 1965 until 1967 for use in the Jeep Wagoneer SUV and Gladiator pick-up truck. Jeep named it the "Vigilante" V8. Two-barrel carburation was standard on these Jeep models, but a four-barrel high-compression version was available in the highly optioned Super Wagoneer from 1966 until 1968. Kaiser-Jeep switched to the Buick 350 in 1967 after AMC discontinued the 327. The Buick V8 engine option continued through 1971 after which Jeeps returned to AMC V8 engines, American Motors having purchased Jeep from Kaiser in 1970. There were low- and high-compression versions of the 327 starting in 1960. Prior to 1960, all 327s were high compression. All low-compression models used a two-barrel carburetor and all high-compression models received a four-barrel carb. The low compression of 8.7:1 and high of 9.7:1 was affected by a difference in pistons. The AMC 327 was also offered as a marine engine as the "Fireball" by Gray Marine Motor Company. Electronic fuel injection The AMC 327 was to be the first commercial electronic fuel injected (EFI) "Electrojector" production engine. Press reports about the Bendix-developed system in December 1956 were followed in March 1957 by an AMC price bulletin offering the EFI option on the Rambler Rebel for US$395, but due to supplier difficulties, fuel-injected Rebels were only available after 15 June. Teething problems with the Electrojector unit meant that only a few engineering and press cars were built, estimated to be no more than six units. At least two pre-production Rebels with EFI, however, are known to have been built. One was sent to Daytona Beach, Florida for "Speed Week" (the forerunner of today's Daytona 500). It was the second fastest car on the beach, bested only by a 1957 Chevrolet Corvette with mechanical fuel injection, and only by a couple of tenths of a second. The EFI 327 was rated at and the regular four-barrel carbureted model at . The EFI system in the Rebel was a far more-advanced setup than the mechanical types then appearing on the market and the engines ran fine in warm weather, but suffered hard starting in cooler temperatures. All the EFI cars were reportedly converted to four-barrel carbs before being sold; none are known to have
