The
Design
The Hurricane was based on the earlier Go-Devil flathead engine. To enhance power from the engine, the induction system was changed from the Go-Devil's side-valve configuration to an inlet-over-exhaust configuration, or "F-head". This allowed the valves to be larger and the combustion chamber to be smaller, improving flow and increasing the compression ratio.[2] The compression ratio rose from 6.5:1 in the Go-Devil engine to 7.5:1 in the Hurricane engine, although a version of the Hurricane engine was made with a 6.9:1 compression ratio.[3]
F134
The L134 Go Devil was updated with the F-head to become the F134 in 1950.[4][5] This engine produced a gross output of 75 hp (56 kW; 76 PS) at 4000 rpm and 114 lb⋅ft (155 N⋅m) of torque at 2000 rpm with a 7.5:1 compression ratio. The gross power and torque outputs decreased to 72 hp (54 kW; 73 PS) and 112 lb⋅ft (152 N⋅m), respectively, when the engine had a 6.9:1 compression ratio. Bore and stroke dimensions were the same as the L-head engine at 3+1⁄8 x 4+3⁄8 inches, giving 134.2 cu in (2,199 cc).[3]
The F4-134 was introduced in 1950 in the Jeep Truck.[4] Willys vehicles with this engine were designated 4-73 model.[6] This engine was unavailable in the CJ series until the introduction of the CJ-3B version in 1953, which had a distinctive high hood to accommodate the much taller engine.[2] Production of this engine continued through 1971, which was after American Motors Corporation (AMC) purchased Kaiser Jeep in 1970.

F161
The F6-161 Hurricane is an F-head version of the L6-161 Lightning flathead straight six. It was available in the Model 685 Station Wagon.[7]
BF-161 The BF-161 has a 3+1⁄8 inch bore and a 3+1⁄2 inch stroke, a one-barrel carburetor, and an output of 90 hp (67 kW; 91 PS) at 4400 rpm and 135 lb⋅ft (183 N⋅m) of torque at 2000 rpm. Its 161.1 cu in (2,640 cc) displacement features a compression ratio of 7.6:1.[8]
2600 The 2600 was the same BF-161 engine made in Brazil by Willys-Overland's subsidiary, but it had two one-barrel carburetors (simultaneously opened) and had an output of 130 hp (97 kW; 132 PS) at 4400 rpm and 140 lb⋅ft (190 N⋅m) of torque at 2000 rpm. The compression ratio remained 7.6:1.[8]
3000 The 3 L version is almost identical to the BF-161 engine, with the stroke increased to 4 inches (101.6 mm), giving it a displacement of 3,016.5 cc (184.1 cu in).[8] With a two-barrel carburetor, it produced 140 hp (104 kW; 142 PS) at 4400 rpm and 161 lb⋅ft (218 N⋅m) of torque at 2000 rpm. It also had a slightly higher compression ratio of 8:1.[8] It initially used a different head with a removable intake manifold.
After Ford acquired Willys-Overland do Brasil, they reverted the engine to its former head design with an integral intake manifold. Ford also improved the cooling between cylinders 5 and 6 as well as incorporating a side-mounted oil filter instead of the front-mounted, hose-connected system designed by Willys.
Applications:
- 1951–1952 Willys Aero
- 1960–1971 Willys Aero 2600
- 1960-1974 Willys-Overland Jeep and Rural Willys
- 1968–1971 Willys Itamaraty 3000
- 1972-1974 Ford Maverick six-cylinder version in Brazil

Mitsubishi versions
Mitsubishi built a version of the Hurricane from 1954 as the JH4 (69 hp), primarily for use in their license-built version of the
Stellantis engine
The 3.0-liter inline-6, called Hurricane turbo engine, developed in 2022 for use in Ram, Jeep, and Dodge vehicles, is unrelated to the original Willys Hurricane versions.[15][16][17]
