How would you tell a 54 from a 55-1st truck engine without knowing the engine code?
One of the things "amiss" is the color.
There is no difference between a 54 and a 55 1st series except the code next to the distributor.
After doing extensive research, it has been determined that a shade of orange/red was used on engines in the Baltimore truck assembly plant (in honor of the first year of the Orioles).

The engine has obviously been repainted.
