![]() Buyers had a choice of several other V8 engines until the end of production in 1988. The company also offered an AMC 304 cubic inch (5.0 L) 210-horsepower V8 as an optional engine from 1971 to 1972 and replaced the six-cylinder with a 4.2L inline-six producing 112 horsepower. Jeep started the 1970s offering its trucks with a standard straight-six engine, an optional 5.4-liter V-8 with 250 horsepower, and a Buick 5.7-liter V-8 that produced 230 horsepower. The CJ-5 is one of the best Jeeps of all time for its longevity and for helping make off-roading accessible to buyers looking for a comfortable ride. Jeep stretched the hood and fenders five inches (127 mm) and the wheelbase three inches (75 mm) to make room for the upgraded engine. According to Motor Trend, perhaps the most significant change to the CJ-5 occurred in 1972 when the American Motors (AMC) company, that had replaced Kaiser ownership in 1970, retired the GM engine replacing it with its own engine: the one-barrel 248 cubic inch (4.2L) and the AMC 304 cubic inch (5L) V-8 engine. Several engines powered the CJ-5 during its lifetime, including the original Willys "Hurricane" F-head four-cylinder and the Buick 155 horsepower 225 cubic inch (3.7L) V-6 Dauntless. Exterior equipment options included front Power Take-Off (PTO), rear PTO, capstan winch, belt pulley drive, rear hydraulic lift, snowplow, welder, generator, heavy-duty springs, driveshaft guards, and side steps.įurthermore, Jeep made many modifications to the CJ-5, evolving the model from a short low-geared, underpowered post-WWII military vehicle into one of the first Jeeps with a pushrod V-8. Willys-Overland offered several options for the CJ-2A, including a front passenger seat, rear seat, canvas top, and heater for the cabin. However, the newer CJ-2A is most easily distinguished from the MB by its large and flush-mounted headlights and the seven-slot front grille that replaced the MB's nine-slot grille. The CJ-2A T-90 three-speed transmission replaced the MB's T-84. ![]() The L-134 Go-Devil engine, with a displacement of 134.2 cubic inches, an L-head design with valves parallel to the cylinders, produced 60 hp at 4000 rpm and 105 lb-ft of torque at 2000 rpm. The first batch of Willys-Overland CJ-2A models, referred to as the "Universal Jeep," used the same powerplant as the MB. The CJ-2A shared DNA with its military ancestor, the MB, featuring an open body, no doors, and the same tailgate and side-mounted spare wheel. The heavy combat wheels bolt together to facilitate field repair and transport the vehicle for a significant distance on deflated tires. Willys stained the MB dark green with a special paint that did not shine in the sun to camouflage it from the enemy. The windshield folded flat on the hood to reduce the vehicle's visible shape and permit aiming and shooting a weapon straight ahead. Willys mounted hand-operated wipers on each side of the windshield. ![]() The body was entirely open with no doors allowing the driver and passengers to quickly jump in or out under extreme conditions. ![]() Willys designed the vehicle for the most demanding and extreme military and off-road conditions. The Army's vehicle specifications included four-wheel drive, a crew capacity of three, 75 inches or less wheelbase, a fold-down windshield, an engine producing 85 lb-ft (115 N m) of torque, an empty weight not exceeding 1,300 pounds (590 kg), and a 660 pounds payload. The Willys MB met the requirements (except for the weight) with a 134.2 cubic inch four-cylinder engine producing 60 horsepower at 3600 rpm and 95 lb-ft of torque at 4000 rpm. ![]()
