LeBlond radial engines

Products

;LeBlond 40-3:3-cylinder air-cooled radial engine. ;LeBlond 60-5D :Introduced in 1928, the 60-5D was a 60 hp (45 kw) 5-cylinder, air-cooled, radial piston engine with a displacement of 234 cuin (3.8 L). This model used iron cylinder heads and was a direct development of the Detroit Air-Cat. ;LeBlond 70-5DE :Introduced in 1930, the 70-5F was a 70 hp (52 kw) at 1,950 rpm 5-cylinder, air-cooled, radial piston engine, (4.125 x 3.75 = 250.57 cuin (4.11 L)), using iron cylinder heads and two bearings. ;LeBlond 85-5DF :Introduced in 1930, the 85-5F was an 85 hp (63 kw) at 1,975 rpm 5-cylinder, air-cooled, radial piston engine, (4.25 x 3.75 = 265.99 (4.36 L)), using aluminum cylinder heads and three bearings. ;LeBlond 70-5E :Introduced in 1930, the 70-5E was a 70 hp (52 kw) 5-cylinder, air-cooled, radial piston engine. Production of the 5E continued under Ken-Royce Engines as the Ken-Royce 5E. ;LeBlond 80-5F :Introduced in 1930, This engine was the last of the so-called 'greasers'. Production of the 5F continued under Ken-Royce Engines as the Ken-Royce 5G. ;LeBlond 85-5DF :Introduced in 1930, the 85-5F was an 85 hp (63 kw) 5-cylinder, air-cooled, radial piston engine with a displacement of 266 cubic inches (4.4 litres) ;LeBlond 90-5F :Introduced in 1930, the 90-5F was a 90 hp (68 kw) 5-cylinder, air-cooled, radial piston engine with a displacement of 266 cubic inches (4.4 litres) ;LeBlond 90-5G :Introduced in 1930, the 90-5G was a 90 hp (68 kw) 5-cylinder, air-cooled, radial piston engine with a displacement of 266 cubic inches (4.4 litres) Production of the 5G continued under Ken-Royce Engines as the Ken-Royce 5G. ;LeBlond 90-7D: 90 hp (67.1 kW) at 1,975rpm 4.125 x 3.75 = 350.81 cu in (5.75 L) ;LeBlond 110-7DF:110 hp (82.1 kW) at 2,150rpm 4.25 x 3.75 = 372.39 cu in (6.10 L) ;LeBlond 120-7 ;Ken-Royce 7F :Introduced by Ken-Royce Engines in 1939 as a 120hp development of the LeBlond 7DF by increasing the compression ratio and changing the intake and carburetor.
