"Blue Flame Six" was the name given to the high-pressure 235 car engines.
http://www.54classicchevy.com/engines.htmlThe "Blue Flame Six" decal was only placed on the blue-painted car engines. The 6-cylinder high-pressure truck engines from 1954 through at least 1960 were named the Thriftmaster, Loadmaster, and Jobmaster engines. From 1955 onwards (through at least 1960), the names Trademaster and Taskmaster were give to different versions of the V-8 truck engines.
Just to confused things further, there was a 322 Loadmaster truck engine in 1956 but that 322 engine might not have been called a Loadmaster in 57-59.
The high-pressure 235 truck engines were supposedly gray through 1959. No one really knows how different the shades of blue were in the later (60-62) 235 car (blue) and truck (blue-gray) engines?
Paint your engine whatever color you like - please yourself, because it is impossible to please everybody when it comes to engine colors.
