Don't know about 1934, but if I read correctly, my 1935-40 Thompson manual says that 1935 Chevrolet car (Master, Standard) and truck (model ''EB'' 1/2 Ton.) (model ''Q'' one and 1 1/2 Ton.) all use the same 206.8 cu.in. engine with different horsepower rating.

Master ''EA-ED'' = 80 HP at 3200
Standard ''EC'' = 74 HP at 3200
''EB''- ''Q'' = 68.5 HP at 3200
